A high-speed photograph of a club hitting a golf ball is shown in the figure below. The club was in contact with a ball, initially at rest, for about 0.0038 s. If the ball has a mass of 55 g and leaves the head of the club with a speed of 2.5 102 ft/s, find the average force exerted on the ball by the club?
