Homework Statement
The Figure shows an approximate representation of the contact force versus time during the collision of a 42-g tennis ball with a wall. The initial velocity of the ball is 35 m/s perpendicular to the wall; it rebounds with the same speed, also perpendicular to the wall. What is the maximum value of the contact force during the collision?
Homework Equations
P = mv
The Attempt at a Solution
I know P = 35 (42/1000) = 1.47 N*m
What is next step? Thank you!
