A 60 g tennis ball with an initial speed of 37 m/s hits a wall and rebounds with the same speed. (Figure 1) shows the force of the wall on the ball during the collision. Figure1 of 1 The plot shows the magnitude of the force as a function of time in milliseconds. No units for the force are given. The magnitude increases linearly from 0 milliseconds and 0 to 2 milliseconds and F subscript max. It stays at this value until 4 milliseconds and then linearly decreases to 6 milliseconds and 0. Part A What is the value of Fmax , the maximum value of the contact force during the collision? Express your answer to two significant figures and include the appropriate units.
