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?

Data From 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 v_f = 55 m/s.?
