A basketball of mass 0.551 kg is dropped from rest from a height of 1.29 m. It rebounds to a height of 0.665 m. (a) How much mechanical energy was lost during the collision with the floor? (b) A basketball player dribbles the ball from a height of 1.29 m by exerting a constant downward force on it for a distance of 0.0988 m. In dribbling, the player compensates for the mechanical energy lost during each bounce. If the ball now returns to a height of 1.29 m, what is the magnitude of the force?
