Racquetball strikes a 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?

The  average acceleration of the racket is 2,800 m/s²

The given parameters include;

initial speed of the racket, u = 30 m/s

recoil velocity of the racket, v = 26 m/s

time of collision, t = 20 m/s

To find:

Let the backward or recoil velocity be in negative direction

The average acceleration of the racket is calculated as;

Thus, the  average acceleration of the racket is 2,800 m/s²

Vo = 30 m/s Vf = 26 m/s, t = 20ms = 0.02s

A = Vo + Vf / t

A = 30 + 26 / 0.02

A = 56 /0.02

A = 2800 m/s^2

dopamine..

"it was found that some people who were taking the drug l-dopa to raise their levels of dopamine were developing schizophrenic-like symptoms supporting research a strength of the dopamine hypothesis is that there are many studies which have shown support for the neurochemical explanation."
