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.
