A rubber ball of mass m = 0.739 kg is dropped from a height ho = 4.73 m, and it rebounds to a height hf = 3.66 m. Assume there is no air friction. a) Find J, the magnitude of the impulse exerted by the ground on the ball. N.s b) If the ground exerts an average force of magnitude F = 727 N on the ball, find tcontact, the time the ball was in contact with the ground. s c) Find ΔE, the energy lost during the collision between the ball and the ground. (NOTE: Energy lost is positive.) J
