V1 = -45 m/s.
V2 = 30 m/s.
a = (V2-V1)/t = (30-(-45))/1.2 =
A professional baseball player pitchers a ball giving it a velocity of 45m/s towards the butter. The batted ball has a velocity of 30m/s towards the pitcher. Let the direction from the batter to the pitcher be the positive direction. If the change in velocity takes place over a period of 1.2s, what was the average acceleration of the baseball?
