24. A 78 g steel ball is released from rest and falls vertically onto a rigid surface. The ball strikes the
surface and is in contact with it for 0.5 ms. The ball rebounds elastically, and returns to its original height
during a round trip of 4 s. Assume that the surface does not deform during contact. What is the
maximum elastic energy stored by the ball? (Use acceleration due to gravity g = 10 m/s2)
