A ball of mass 1 kg is dropped from 20 m height on the ground and it rebounds to height 5 m . Find the magnitude of change in momentum duribg its collidion with the ground.Pls help experts.
Velocity of the ball when it hit the ground can be calculated as
on striking the ground let the ball rebound with the velocity u in upward direction. it can be calculated as
Change in momentum of the ball = final momentum of the ball initial momentum of the ball
=
