## Homework Statement

A 3.00 kg stell ball strikes a wall with a speed of 9.0m/s at an angle of 60° with the surface. It bounces off with the same speed and angle. If the ball is in contact with the wall for .200 s, what is the average force exerted by the wall on the ball?

## Homework Equations

ΣFavg=1/Δt integral ΣFdt from ti to tf

## The Attempt at a Solution

F avg=1/.200(3.00kg)(9.8m/s^2)x|0 to .200

=29.4N

Could someone please tell me if this looks correct and if now could someone please show me where I went wrong?

Thank you very much
