A 50 gram ball is thrown at a wall and bounces off. Its speed just before impact is 24 m/s and its speed just after hitting the wall is 22 m/s in the opposite direction. If the ball is in contact with the wall for 3.5 ms, what is the magnitude of the average acceleration of the ball while it is in contact with the wall?
