A tennis player strikes the tennis ball with her racket while the ball is still rising. The ball speed before impact with the racket is v₁ - 16 m/s and after impact its speed is v₂ - 22 m/s, with directions as shown in the figure. If the 60-g ball is in contact with the racket for 0.045 s, determine the magnitude of the average force R exerted by the racket on the ball. Find the angle 3 made by R with the horizontal, Comment on the treatment of the ball weight during impact. Assume 8-23° -11%
