A ball of mass 160 g is released from rest at a height of2.10 m above the floor and it rebounds straight up to a height of 0.900 m.
Decide the magnitude of the ball's change in momentum due to its contact with the floor.
If the contact time by the floor was0.0950 s, what was the average force the floor exerted on the ball?
