(b) What force does the pltcher exert on the bal? Need Holp? eac Show My Work can subril show my wok an unimited namber of times

Explanation / Answer

(a) The acceleration imparted by the pitcher is v/t = vi/t. The distance moved under uniform acceleration a is 0.5*a*t² substitute for a to get

s = 0.5*(v/t)*t² = 0.5*v*t

(b) The mass of the ball is Fg/g. The force imparted in the i direction by the pitcher is M*a. The i force component is then

Fi = (Fg/g)*0.5*v*t

The j component is +Fg (to keep the motion horizontal and counteract gravity). The total force exerted by the pitcher is then

F = [Fi² + Fg²]

The angle of the force is arctan(Fg/Fi)
