A baseball player hits a baseball (m = 0.14 kg) as shown in Figure P7.11. The ball is initially traveling horizontally with a speed of 40 m/s. The batter hits a fly ball as shown, with speed v_f= 55 m/s.?

(a) What are the magnitude and direction of the impulse imparted to the ball??

(b) If the ball and bat are in contact for a time of 8.0 ms, what is the magnitude of the average force of the bat on the ball? Compare this answer to the weight of the ball.?
