Abaseball pitcher throws a baseball with a speed of 42 m/s . in throwing the baseball, the pitcher accelerates it through a displacement of about 3.5 m, from behind the body to the point where it is released.

a = 252 m / s²

Explanation:

The initial speed Vο = 0

The speed of baseball with witch it is thrown  Vf = 42 m/s

Displacement covered = 3.5 m

Hence acceleration will be constant at this moment, so as per the equation of constant acceleration : ( Vf² - Vο² ) / 2d = a

                                                            a = 252 m / s²

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."
