Question

6. A tennis player strikes a tennis ball with her racket when the ball is at the uppermost point of its trajectory as shown. Just after impact, the velocity of the ball is directed at an angle of 15° above the horizontal. If the 125 gram ball is in contact with the racket for 0.02 sec, and the average impulsive force exerted by the racket on the ball is of magnitude of 200 N and directed at an angle 9° above the horizontal, determine: (a) the magnitude of velocity V2 (m/s) of the ball just after impact; (b) the magnitude of velocity v1 (m/s) of the ball just before impact You may neglect the effect of gravity during the impact.
