The gravitational force exerted on a baseball is -Feg j^. A pitcher throws the ball with velocity v i ^ by uniformly accelerating it along a straight horizontal line for a time interval of Delta t = t - 0 = t. (a) Starting from rest, through what distance does the ball move before its release? (b) What force does the pitcher exert on the ball?
