A basketball of mass 0.45 kg is dropped from rest from a height of 1.22 m. It rebounds to a height of 0.72 m.

(a) How much mechanical energy was lost during the collision with the floor?

J

(b) A basketball player dribbles the ball from a height of 1.22 m by exerting a constant downward force on it for a distance of 0.13 m. In dribbling, the player compensates for the mechanical energy lost during each bounce. If the ball now returns to a height of 1.22 m, what is the magnitude of the force?
