A 4.30-kg steel ball strikes a wall with a speed of 7.0 m/s at an angle of ? = 60.0 with the surface. It bounces off with the same speed and angle (see figure below). If the ball is in contact with the wall for 0.200 s, what is the average force exerted by the wall on the ball? (Assume right and up are the positive directions.)

Fx?=___________ N

Fy?=___________ N
