moving perpendicular to a wall. After striking

the wall, the ball rebounds in the opposite

direction with a speed of 11.4 m/s.

If the ball is in contact with the wall for

0.0139 s, what is the average acceleration of

the ball while it is in contact with the wall?

Take “toward the wall” to be the positive

direction.

Answer in units of m/s2
