A racquetball strikes a wall with a speed of 30 m/s and rebounds with a speed of 26 m/s. The collision takes 20 ms. What is the average acceleration of the ball during collision?
Added by Jessica M.
Step 1
First, we need to find the change in velocity. The ball initially moves at 30 m/s and rebounds at -26 m/s (negative because it's in the opposite direction). So, the change in velocity is -26 m/s - 30 m/s = -56 m/s. Show more…
