The baseball in Problem 11 is replaced by a very flexible rubber ball of equal mass. (a) Does the contact time increase or decrease? (b) If the contact time changes by a factor of 50 but the initial and final velocities are the same, by what factor does the force of the bat on the ball change?

(reference problem 11)

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 (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. (c) What is the impulse imparted to the bat?
