# Question: A rubber ball is attached to a paddle by a

A rubber ball is attached to a paddle by a rubber band.

The ball is initially moving away from the paddle with a speed of 4.0 m/s. After 0.25 s, the ball is moving toward the paddle with a speed of 3.0 m/s. What is the average acceleration of the ball during that 0.25 s? Give magnitude and direction.
