Homework Statement
A 67.6g tennis ball with an initial speed of 28.8m/s hits a wall and rebounds with the same speed. The figure below shows the force of the wall on the ball during the collision. What is the value of Fmax, the maximum value of the contact force during the collision, if the force is applied for ti=19.1ms?
Homework Equations
I= pf-pi
I= area under the curvehttp://s1329.photobucket.com/user/GarrettSPB/media/momentum_zps3611f797.png.html
The Attempt at a Solution
I was able to find the impulse as the difference between the initial and final momentum. This ended up being 3.89 N*s. From that I know how to find Favg, but I'm stuck on how to find Fmax. Any suggestions would be appreciated.
