A ball is dropped from the height of 2.0m and it bounced three times on the floor before coming to a halt. The maximum rebound height of the ball reduces with each subsequent bounce. Assuming that all downward motion is in the positive direction, sketch the graph of velocity against time to depict the motion of the ball as it bounces three times.
What is the ball's centripetal acceleration just before it is released? What is the magnitude of the net force that is acting on the ball just before it is released?
