1:08:22 Hw 1 -: Given - U = 0 V= 40 km/h Therefore by converting it we get v = 11.11 m/s And t= 600 (s) Now acceleration = V-U/ t By substituting the values =11.11-0/600 Which gives a= 0.0185 m/s^2 I hope I am correct
H.W.1.---------------- U(initial velocity)=0 v(final velocity) = 100/9 m/s time duration = 10*60s = 600s Acceleration (a) = (v-u)/t a= (100/9) m/s/600 s = 0.0185 m/s² (approx). or Initial velocity of the train, u = 0 (since the train is initially at rest) Final velocity of the train, v = 40 km/h = 40*5/18 = 11.11 m/s Time taken, t = 10 min = 10 × 60 = 600 s Acceleration = a= v-u/t = 11.11 * o/600 = 0.0185 m/s2 Hence, the acceleration of the train is 0.0185 m/s2. I HOPE THIS WILL HELP YOU, AND ALL THANKS TO THE TEACHER, 😁

30:45 Amar's and Anthony's car speed are in *uniform motion* as they are covering equal distance in equal time interval. Whereas, Akbar's car speed is in *non-uniform motion* because the speed is changing.
To find the acceleration of train, we can following the formula:- A = u - v /t Given:- U = 0 [ as the train start from rest ] V = 40 km/h T = 10 minutes = 10/60 hours = 1/6 hours Now, let's calculate the acceleration using the given values :- A = U - V/ T = 0 - 40 = 40 km/h = 40 km/h / (1/6) = 40* 6 km/h = 240 km/ h²

You get 0 out of 100😂
This is a new institute 😂😂 of getting 98% out of 100% by a like
01:08:12 - Answer is:
Initial position (u) = 0 m/s²
Final position (v) = 40 km/h = 40 x 5/18 = 200/18
time (t) = 10 minutes = 10 * 60 = 600 seconds
a = v - u / t
so, (200/18 - 0/18) / 600 = 200 - 0 / 600 * 18 = 200 / 10800 = 2/108 = 1/54
Hence, acceleration = 1 / 54 m/s²
Thanks you confirm my ans

Yes, this is the correct answer
Bro why you took m/s² as initial velocity this is not acceleration

H.W.1.---------------- U(initial velocity)=0
v(final velocity) = 100/9 m/s
time duration = 10*60s = 600s
Acceleration (a) = (v-u)/t
a= (100/9) m/s/600 s = 0.0185 m/s² (approx).
or
Initial velocity of the train, u = 0 (since the train is initially at rest)
Final velocity of the train, v = 40 km/h = 40*5/18 = 11.11 m/s
Time taken, t = 10 min = 10 × 60 = 600 s
Acceleration = a= v-u/t = 11.11 * o/600 = 0.0185 m/s2

FOURTH LAW OF MOTION:-
Every book remains at the state of rest until and unless any external or internal exams appear, and then the speed of turning pages will be directly proportional to the amount of syllabus to be completed in time and the tension in mind remains constant...

Velocity= V-U/t

V-U= 40km/hr (bcs its uniform)
Converting it to m/s
40×5/18 = 200/18 m/s
Now V-U/t

30:45 Amar's and Anthony's car speed are in *uniform motion* as they are covering equal distance in equal time interval.
Whereas, Akbar's car speed is in *non-uniform motion* because the speed is changing.
Bcz acceleration is changing
Ravi Teja movie
To find the acceleration of train, we can following the formula:-
A = u - v /t
Given:-
U = 0 [ as the train start from rest ]
V = 40 km/h
T = 10 minutes
= 10/60 hours
= 1/6 hours
Now, let's calculate the acceleration using the given values :-
A = U - V/ T
= 0 - 40
= 40 km/h
= 40 km/h / (1/6)
= 40* 6 km/h
= 240 km/ h²
I wish everyone got 98 percent in their final term
Newton's 4th laws says that every book continuous to be in rest until and unless internal and external exam appear and speed of page turning is directly proportional to the syllabus to be cover and tension in the mind remain constant
😂😂
😅😅
Newtons's Law of Ashiqui:-
Every ashiqui continues to do ashiqui until an internal or external,i.e, by home or girl's family, 'flying chapal' is thrown upon his face by a 'lovely girl'.
This external/internal 'flying chapal' is called 'Bezzati' which is directly proportional to 'Besharmi', however,'Bezzati remains constant.

Yes when that object reached to the same initial point therefore displacement =0
I understand this full chapter 👍... Thank you so much😊 sir... For explain this chapter
Amazing lecture ❤❤
I hope I will get good marks with amazing lecture+ my hard work ❤❤
Que 1 =16m
Que 2 =0
Que 3=magnitude and direction
Que 4=distance > displacement
Que 5=vector
Que 6= yes if the object have same starting and ending point
Kitne chapter ho gye 😅

5--->>>>vector quantity
*?*--->>>>Yes it can be 0 as if an object(x) has to reach the initial to final destination and it is the same (y) then , the displacement must be 0.
1:35:57 Sir, The acceleration is 2cm/s^2 not 2m/s^2. So, the final answer will be 0.06m/s^2

Time 1:32:15
Ans - slope = acceleration =1.6m/s²
Homework 1:-
Initial velocity or u= 0 m/s
Final velocity or v= 40×100÷3600m/s
=11.1m/s
Time taken or t= 10 minutes
10×60second
= 600 seconds
Accerleration or a=
Final velocity(v) - Initial velocity(u) ÷ time taken(t)
= 11.1 - 0 ÷ 600
=0.0185 m/s square
1:08:30 H. W 1 ans 0.0185m/s²
Mera bhi yahi aaya kya ye sahi hai ??
I wish that you all da a great job 👍
