(ii) (5 pts) A tennis ball of mass 0.060 kg with initial speed v, = 40 m/s hits a wall and rebounds with a speed of v, = 34 m/s. a) What is the change in momentum of the tennis ball? b) The next figure shows the force of the wall on the tennis ball during the collision. What is the magnitude of the maximum force Fmax? (Pay attention to the units in the graph. (1ms = 0.001 sec) F (N) max
