A tennis ball has a mass of 0.051 kg. A professional tennis player hits the ball hard enough to give it a speed of 47 m/s (about 105 miles per hour.) The ball moves toward the left, hits a wall and bounces straight back to the right with almost the same speed (47 m/s). As indicated in the diagram below, high-speed photography shows that the ball is crushed about d = 2.5 cm at the instant when its speed i momentarily zero, before rebounding. d D Making the very rough approximation that the large force that the wall exerts on the ball is approximately constant during contact, determine the approximate magnitude of this force. Part 1 (a) What is the average speed of the ball during the period from first contact with the wall to the moment the ball's speed is momentarily zero? |ag| = Save for Later Part 2 m/s (b) How much time elapses between first contact with the wall, and coming to a stop?
