The gravitational force exerted on a baseball is 2.25 N down. A pitcher throws the ball horizontally with velocity 15.5 m/s by uniformly accelerating it along a straight horizontal line for a time interval of 154 ms. The ball starts from rest.
(a) Through what distance does it move before its release?: 1.19m (answer for a), acceleration in the small period of time of the pitcher throwing the ball is 100.65m/s/s.
(b) What are the magnitude and direction of the force the pitcher exerts on the ball? Magnitude: ____ N Direction: _______ (degrees) above horizontal
