Question

if the time is taken to bring a ball to rest from a certain velocity 'v'. is reduced to half, what will be the change in the values of a) initial momentum b) final momentum c) rate of change of momentum?

Answer 1

The answer is C) rate of change of momentum. The answer is not initial or final momentum as the start and end points are not changing. On the other hand, the time it takes for the ball to change velocity is. This change relates to the change of momentum. Hope this helped :))
