A player hits a 2-oz tennis ball with a horizontal initial velocity of 54 ft/s at a height of 4.5 ft. The ball bounces at point A and rises to a maximum height of 3 ft where the velocity is 30 ft/s, knowing that the duration of the impact is 0.004s determine the impulsive force exerted on the ball at point A.

51 ft 4.5 ft 30 ft/s [3 ft
