1:12:32 full explanation of answer is: Mass= 10 kg initial velocity= 15m/s final velocity=0(as when object is thrown vertically upwards the final velocity is considered 0) so at height 0 in bottom, the total energy acting in the ball would be kinetic, as the height is 0 and for potential energy you need some height so Total Energy= Kinetic Energy at bottom 1/2mv^2 1/2x10x15x15 1/2x10x225 1125 J so at heighest height for a fraction of time the object has 0 velocity which means it has potential energy at the top. so total energy at top = Potential energy 1125 = mgh 1125=10x10xh 1125/100= h 11.25m In this answer i have considered acceleration due to gravity to be 10, you can try with 9.8 also. edit: You can simply use the third equation of motion to understand but I tried to explain it conceptually.

1:12:32 Guyss simple hai listen here... 💗 m=10kg u=15m/s v=0m/s (as ball jab vertically upward jayega to iska final velocity jo hai vo 0 hogi) K.E = 1/2•m(v²- u²) K.E = 1/2•10(0²-15²) K.E = 1/2•10(-15²) K.E = 1/2•10•225 K.E = 1125 💗 Law of Conservation k hisaab se K.E = P.E So, I have assumed g=10m/s² P.E = mgh 1125 = mgh 1125 =10•10•h 1125= 100•h h = 1125/100 h = 11.25 Hence... The ball reach maximum height of 11.25m approx. (Guys iska answer g ki value pe depend karta hai💗 ) (Agar apne assume g=10m/s² kiya hai to apka ans 11.25m ayega💗) (Aur agar apne assume g=9.81m/s²kiya hai to ans 11.48m ayega 💗) But dono hi answer sahi hai💗
Sir please teach these chapters:-😢 1. Improvement in food resources(done)🎉 2. Structure of the atoms(done) 3. Sound(needed urgently) Edited:- Thank u for 30 likes
1:12:11 Here's how to calculate the maximum height reached by the ball using the law of conservation of energy: 1. Initial Kinetic Energy: The ball is thrown upward with an initial velocity, so it possesses kinetic energy. The formula for kinetic energy is: Kinetic Energy (KE) = 0.5 * mass * velocity^2 Substituting the given values: KE = 0.5 * 10 kg * (15 m/s)^2 = 1125 Joules 2. Potential Energy at Maximum Height: At the maximum height, the ball's velocity becomes zero, meaning its kinetic energy is converted entirely into potential energy. The formula for potential energy is: Potential Energy (PE) = mass * gravity * height 3. Equating Kinetic and Potential Energy: According to the law of conservation of energy, the initial kinetic energy equals the potential energy at the maximum height: KE = PE Substituting the values: 1125 Joules = 10 kg * 9.81 m/s^2 * height 4. Solving for Height: Rearranging the equation to solve for height: height = 1125 Joules / (10 kg * 9.81 m/s^2) ≈ 11.47 meters Therefore, the maximum height reached by the ball is approximately 11.47 meters.

#1:12:32 we know that k.e=1/2m(v^2-u^2) and p.e = mgh Given= u=15m/s v=0m/s h=? gravational force=-10m/s^2 according to the law of conservation of energy k.e=p.e 1/2*m(0^2-15^2)=m*-g*h ( since gravitational force always act opposite) 1/2(-15^2)=-10*h 1/2*225=10h 1/2*225/10=h 225/20=h 11.25=h therefore the max height is 11.25m Check v^2-u^2=2as -u^2=-2gh -225=-20h 225/20=h h=11.25 m

m = 10 u. = 15 v = 0 at the bottom,KE = 1/2 × m × v² = 1125J And PE = 0 at the bottom Total E = KE+PE Total E = 1125 Now, At the top KE = 0 So,Total energy= PE + KE 1125 = PE + 0 PE= 1125 Now, PE = mgh =10×10×h = 1125 = 1125/100= 11.25m Thanks, 😊
1:12:32 Agar Mgh se karoge toh ayyega 150m, Jo ki shyd wrong ha Lekin agar v(2)-u(2)=2as se karoge toh ayyega 11.25 m Itna Likha ha like toh de do ek Agar samj ayye toh de Dena 😊😅
Bhaiya we need these chapter 1. Sound. 2. Improvement in food resource . 3. Structure of Atom.. bhaiya 10 nov. se phle read krwa dijiye bczz. hamlogo ka school open ho jayega after 10 nov..therefore I will humbly request you...❤
To calculate the maximum height reached by the ball using the law of conservation of energy, we equate the ball's initial kinetic energy to its potential energy at the maximum height, where all kinetic energy is converted into potential energy. Given Data: Mass of the ball, m=10 kgm = 10 \, \text{kg} Initial velocity, u=15 m/su = 15 \, \text{m/s} Acceleration due to gravity, g=9.8 m/s2g = 9.8 \, \text{m/s}^2 Step 1: Kinetic Energy at Launch The initial kinetic energy of the ball is: KE=12mu2KE = \frac{1}{2} m u^2 KE=12×10×(15)2=5×225=1125 JKE = \frac{1}{2} \times 10 \times (15)^2 = 5 \times 225 = 1125 \, \text{J} Step 2: Potential Energy at Maximum Height At the maximum height, the ball's potential energy is: PE=mghPE = m g h Step 3: Applying Conservation of Energy At maximum height, KEKE is fully converted into PEPE: KE=PEKE = PE 1125=10×9.8×h1125 = 10 \times 9.8 \times h Step 4: Solve for hh h=112510×9.8=112598≈11.48 mh = \frac{1125}{10 \times 9.8} = \frac{1125}{98} \approx 11.48 \, \text{m} Final Answer: The maximum height reached by the ball is approximately 11.5 meters. 1:12:30
1:31:13 c) it increases, because at a certain height when the ball is about to fall the velocity will be zero. So K.E=1/2mv² =1/2m(0)² =0 J And the potential energy will have some value And when it falls down the potential energy gets converted to kinetic energy . So the correct option will be c) it increased Thank you so much prashant bhaiya for teaching us this lesson. ❤
To determine which ball has more kinetic energy, we need to calculate the kinetic energy of each ball. The formula for kinetic energy is: Kinetic Energy (KE) = 0.5 × mass (m) × velocity (v)² For Ball A: KE = 0.5 × 5 kg × (15 m/s)² = 0.5 × 5 kg × 225 m²/s² = 562.5 J For Ball B: KE = 0.5 × 10 kg × (10 m/s)² = 0.5 × 10 kg × 100 m²/s² = 500 J Comparing the kinetic energies: Ball A (562.5 J) has more kinetic energy than Ball B (500 J). So, Ball A has more kinetic energy.
@@TonmoiNath-w7f Given is m= 10 kg and v = 15 So, k E = 1/2 x 10 x (15)² =1125 so we get k e = 1125 Then mgh = 1125 10*10*h = 1125 100h =1125 H = 1125/100 H = 11.25 m
Bhaiya aap class 9 and 10 science ka concept acche se samjhate ho. Thankyou !!! Koi murkh baccha hi bolta hai like nahi karne se fail ho jayoge but sir hamme aap par aur khud par pura biswas hai😊
A 10 kg ball is thrown vertically upward with an initial velocity of 15 m/s. Calculate the maximum height reached by the ball using the law of conservation of energy. Ignore air resistance. Ans. 5m
hello sir, my half yearly result is announced and I got 98%. Last time in tests I got only 60%,59%. I improve my self and study 13 hour per day . 😢❤😊😊thank you sir once again thank you
I a Chaithanya from" karnataka" (Bangaluru rural) I need to inform you that more than 100 members from our village are learning from your videos even Digraj sir is also the part of our learning from your chanalles only so i saw some of your videos that you had made some of programmes so i request you to come for Bangaluru Thank you sir i had scored 78/80 in science and 80/80 in SST
So, Acc. To ques. 10kg, mass Initial velocity , 15m/s Final , 0 So, Kinatic energy, 1/2 mv"2 So, Acc. To law of conservation of energy the formula is, 1/2 m(v2-u2) 1/2 *10*0*15*15 = 1125 joule So, We have to find a height, So, mgh we have to use mgh potential energy =mgh 1125=10*10*? 1125=100 11.25m ( height) final answer Its deficult but sir said that its easy. I can't believe l solved this question All credits goes to prasant sir Thanks you sir for your super se bhi uper wale lecture ka liye. Thanks for reading my answer. ❤❤❤❤
Bro when we apply force on an object and they move on same direction then the angle formed between f and s is cos 0 and the value of cos 0 is 1 when we multiple f × s × 1=fs🎉

Do not take rest
Because Prashant bhaiya is perfect and best 😂😂😂😂😂❤❤😮😮😅😅
Yes sir😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😮
yes sir 😂😂😂😂😂😂
29:49
Yes sir😂😂😂
Same to you
1:12:32 full explanation of answer is:
Mass= 10 kg
initial velocity= 15m/s
final velocity=0(as when object is thrown vertically upwards the final velocity is considered 0)
so at height 0 in bottom, the total energy acting in the ball would be kinetic, as the height is 0 and for potential energy you need some height
so
Total Energy= Kinetic Energy at bottom
1/2mv^2
1/2x10x15x15
1/2x10x225
1125 J
so at heighest height for a fraction of time the object has 0 velocity which means it has potential energy at the top.
so total energy at top = Potential energy
1125 = mgh
1125=10x10xh
1125/100= h
11.25m
In this answer i have considered acceleration due to gravity to be 10, you can try with 9.8 also.
edit: You can simply use the third equation of motion to understand but I tried to explain it conceptually.
Thanks for reading
Height would be 11.48 m if g= 9.8
No, Gravity is taken as round off and it will be 10 only not 9.8....Actually it is correct in both ways
Ok
just use v^2-u^2=2as
@aaryanpatnaik my answer is in negative like -11.25m . It is correct or not

😂😂😂😂 tune. Pada. Hi. NHi
Yes sir please inke bhi lecture dedo
1:12:32 Guyss simple hai listen here... 💗
m=10kg
u=15m/s
v=0m/s (as ball jab vertically upward jayega to iska final velocity jo hai vo 0 hogi)
K.E = 1/2•m(v²- u²)
K.E = 1/2•10(0²-15²)
K.E = 1/2•10(-15²)
K.E = 1/2•10•225
K.E = 1125 💗
Law of Conservation k hisaab se K.E = P.E
So,
I have assumed g=10m/s²
P.E = mgh
1125 = mgh
1125 =10•10•h
1125= 100•h
h = 1125/100
h = 11.25
Hence... The ball reach maximum height of 11.25m approx.
(Guys iska answer g ki value pe depend karta hai💗 )
(Agar apne assume g=10m/s² kiya hai to apka ans 11.25m ayega💗)
(Aur agar apne assume g=9.81m/s²kiya hai to ans 11.48m ayega 💗)
But dono hi answer sahi hai💗
thanks bro…😊

Here's how to calculate the maximum height reached by the ball using the law of conservation of energy:
1. Initial Kinetic Energy:
The ball is thrown upward with an initial velocity, so it possesses kinetic energy. The formula for kinetic energy is:
Kinetic Energy (KE) = 0.5 * mass * velocity^2
Substituting the given values:
KE = 0.5 * 10 kg * (15 m/s)^2
= 1125 Joules
2. Potential Energy at Maximum Height:
At the maximum height, the ball's velocity becomes zero, meaning its kinetic energy is converted entirely into potential energy. The formula for potential energy is:
Potential Energy (PE) = mass * gravity * height
3. Equating Kinetic and Potential Energy:
According to the law of conservation of energy, the initial kinetic energy equals the potential energy at the maximum height:
KE = PE
Substituting the values:
1125 Joules = 10 kg * 9.81 m/s^2 * height
4. Solving for Height:
Rearranging the equation to solve for height:
height = 1125 Joules / (10 kg * 9.81 m/s^2)
≈ 11.47 meters
Therefore, the maximum height reached by the ball is approximately 11.47 meters.

#1:12:32 we know that k.e=1/2m(v^2-u^2) and p.e = mgh
Given= u=15m/s
v=0m/s
h=?
gravational force=-10m/s^2
according to the law of conservation of energy
k.e=p.e
1/2*m(0^2-15^2)=m*-g*h ( since gravitational force always act opposite)
1/2(-15^2)=-10*h
1/2*225=10h
1/2*225/10=h
225/20=h
11.25=h
therefore the max height is 11.25m
Check
v^2-u^2=2as
-u^2=-2gh
-225=-20h
225/20=h
h=11.25 m
Correct 💯
No .. gravitaional force not always act opposite

Total E = 1125
Now,
At the top KE = 0
So,Total energy= PE + KE
1125 = PE + 0
PE= 1125
Now,
PE = mgh
=10×10×h = 1125
= 1125/100= 11.25m
Thanks, 😊
Very help full
1:12:32 Agar Mgh se karoge toh ayyega 150m, Jo ki shyd wrong ha Lekin agar v(2)-u(2)=2as se karoge toh ayyega 11.25 m

To calculate the maximum height reached by the ball using the law of conservation of energy, we equate the ball's initial kinetic energy to its potential energy at the maximum height, where all kinetic energy is converted into potential energy.
Given Data:
Mass of the ball, m=10 kgm = 10 \, \text{kg}
Initial velocity, u=15 m/su = 15 \, \text{m/s}
Acceleration due to gravity, g=9.8 m/s2g = 9.8 \, \text{m/s}^2
Step 1: Kinetic Energy at Launch
The initial kinetic energy of the ball is:
KE=12mu2KE = \frac{1}{2} m u^2 KE=12×10×(15)2=5×225=1125 JKE = \frac{1}{2} \times 10 \times (15)^2 = 5 \times 225 = 1125 \, \text{J}
Step 2: Potential Energy at Maximum Height
At the maximum height, the ball's potential energy is:
PE=mghPE = m g h
Step 3: Applying Conservation of Energy
At maximum height, KEKE is fully converted into PEPE:
KE=PEKE = PE 1125=10×9.8×h1125 = 10 \times 9.8 \times h
Step 4: Solve for hh
h=112510×9.8=112598≈11.48 mh = \frac{1125}{10 \times 9.8} = \frac{1125}{98} \approx 11.48 \, \text{m}
Final Answer:
The maximum height reached by the ball is approximately 11.5 meters.

1:31:13 c) it increases, because at a certain height when the ball is about to fall the velocity will be zero. So
K.E=1/2mv²
=1/2m(0)²
=0 J
And the potential energy will have some value
And when it falls down the potential energy gets converted to kinetic energy
. So the correct option will be c) it increased

Hii kavya ji nmste

To determine which ball has more kinetic energy, we need to calculate the kinetic energy of each ball.
The formula for kinetic energy is:
Kinetic Energy (KE) = 0.5 × mass (m) × velocity (v)²
For Ball A:
KE = 0.5 × 5 kg × (15 m/s)²
= 0.5 × 5 kg × 225 m²/s²
= 562.5 J
For Ball B:
KE = 0.5 × 10 kg × (10 m/s)²
= 0.5 × 10 kg × 100 m²/s²
= 500 J
Comparing the kinetic energies:
Ball A (562.5 J) has more kinetic energy than Ball B (500 J).
So, Ball A has more kinetic energy.

Explain pls bro
@@TonmoiNath-w7f Given is m= 10 kg and v = 15
So, k E = 1/2 x 10 x (15)²
=1125 so we get k e = 1125
Then mgh = 1125
10*10*h = 1125
100h =1125
H = 1125/100
H = 11.25 m

Thank you sir i had scored 78/80 in science and 80/80 in SST
plz sir coe to bangaluru once
my drea is to meet you once
the arhs i enter above is because of your and Digraj sir's hard work only
So,
Acc. To ques.
10kg, mass
Initial velocity , 15m/s
Final , 0
So,
Kinatic energy, 1/2 mv"2
So,
Acc. To law of conservation of energy the formula is,
1/2 m(v2-u2)
1/2 *10*0*15*15 = 1125 joule
So,
We have to find a height,
So, mgh we have to use mgh potential energy =mgh
1125=10*10*?
1125=100
11.25m ( height) final answer
Its deficult but sir said that its easy. I can't believe l solved this question
All credits goes to prasant sir

Acceleration due to gravity
v2 - u2 = 2-gs
0 + 15 × 15 = 2×-10×s
-225 = -20s
-225/-20 = s
S = 11.25
Ohhh 😮😮
Hiii
Signs me mistake kari hai aapne according to me
It's said find using law of conservation
How is the final velocity 0?
41:27
Ball A k.g.=562.5 Joule
Ball B k.g.=500 Joule
Hence Ball A has more kinetic energy
Correct 💯🔥
