A 69-g steel ball is released from rest and falls vertically onto a steel plate. The ball strikes the plate and is in contact with it for 0.5 ms. The ball rebounds elastically, and returns to its original height. The time interval for a round trip is 6.00 s. In this situation, the average force exerted on the ball through contact with the plate is closest to:
