A racquetball strikes wall with a speed of 30 m/s and rebounds in the opposite direction with a speed of 26 m/s. The collision takes 20 ms. What is the average acceleration of the ball during the collision with the wall?
Added by Stephanie W.
Step 1
The initial velocity (\(v_i\)) is 30 m/s (towards the wall), and the final velocity (\(v_f\)) is -26 m/s (away from the wall, opposite direction). Show more…

A tennis ball with a velocity of $+10.0 \mathrm{m} / \mathrm{s}$ to the right is thrown perpendicularly at a wall. After striking the wall, the ball rebounds in the opposite direction with a velocity of $-8.0 \mathrm{m} / \mathrm{s}$ to the left. If the ball is in contact with the wall for $0.012 \mathrm{s}$, what is the average acceleration of the ball while it is in contact with the wall?
