*DOUBT!!* If there is an object whose mass is less but if its velocity is very high then its momentum will also be high and if we take another example then there is another object whose mass is very high but its velocity is very less then its momentum will also will be too much. So these two can be high momentum right?

Mass of Hockey ball is 0.2 kg Initial velocity = 10 m/s Final velocity = -5m/s Change in momentum = p(final)-p(initial) P(final)=MV =0.2×-5=-1kgm/s P( initial) = MV =0.2×10=2kgm/s We know =P(final)-p(initial) =-1kgm/s-2kgm/s =-3kgm/s
I apologize for the mistake in my previous response. Here's the correct solution: The change in momentum of the hockey ball is given by the formula: Change in momentum = Final momentum - Initial momentum The momentum of the ball before it was struck by the hockey stick is given by: Initial momentum = m x u where m is the mass of the ball and u is its initial velocity. Substituting the given values, we get: Initial momentum = 0.2 kg x 10 m/s = 2 kg m/s The momentum of the ball after it was struck by the hockey stick is given by: Final momentum = m x v where v is the final velocity of the ball. Substituting the given values, we get: Final momentum = 0.2 kg x 5 m/s = 1 kg m/s Therefore, the change in momentum of the hockey ball is: Change in momentum = Final momentum - Initial momentum = 1 kg m/s - 2 kg m/s = -1 kg m/s The negative sign indicates that the direction of the change in momentum is opposite to the direction of motion of the ball. The force applied by the hockey stick can be calculated using the formula: Force = Change in momentum / Time Since we don't know the time of impact, we cannot calculate the force applied by the hockey stick.

35:44 If a man falls on a cement floor made of hard soil, his speed will come to zero in such a short time. Due to which a strong opposing force can act on the person, the rate of change of momentum is very good. This force would seriously injure a man. Rather, falling onto the sand drives the feet deeper into the sand, expending less energy on the sand. So according to Newton's law, the sand only exerts less force on the feet. If a man falls on a sand dune with a soft landing, the man's chances of survival are high. Because loose sand or sand silt reduces the rate of dynamic transition. Due to which the person stops with a little force of sand and does not get hurt. That's why the sand becomes soft and slows down the speed of man.

@AMAR UPADHYAY ..you are right
Mass of Hockey ball is 0.2 kg
Initial velocity = 10 m/s
Final velocity = -5m/s
Change in momentum = p(final)-p(initial)
P(final)=MV
=0.2×-5=-1kgm/s
P( initial) = MV
=0.2×10=2kgm/s
We know
=P(final)-p(initial)
=-1kgm/s-2kgm/s
=-3kgm/s
Good bro
Sir you are the bestest teacher of physics , I had ever be seen, Thankyou sir ......
A secret thing is in physics where ever you see word rate it directly means that you should do /time. It may be helpful for you
Thanks sir to make physics easy for me to understand😊
I apologize for the mistake in my previous response. Here's the correct solution:
The change in momentum of the hockey ball is given by the formula:
Change in momentum = Final momentum - Initial momentum
The momentum of the ball before it was struck by the hockey stick is given by:
Initial momentum = m x u
where m is the mass of the ball and u is its initial velocity.
Substituting the given values, we get:
Initial momentum = 0.2 kg x 10 m/s = 2 kg m/s
The momentum of the ball after it was struck by the hockey stick is given by:
Final momentum = m x v
where v is the final velocity of the ball.
Substituting the given values, we get:
Final momentum = 0.2 kg x 5 m/s = 1 kg m/s
Therefore, the change in momentum of the hockey ball is:
Change in momentum = Final momentum - Initial momentum
= 1 kg m/s - 2 kg m/s
= -1 kg m/s
The negative sign indicates that the direction of the change in momentum is opposite to the direction of motion of the ball.
The force applied by the hockey stick can be calculated using the formula:
Force = Change in momentum / Time
Since we don't know the time of impact, we cannot calculate the force applied by the hockey stick.
