A Fast Pitch.? The fastest measured pitched baseball left the pitcher’s hand at a speed of 45.0 m/s. If the pitcher was in contact with the ball over a distance of 1.50 m and produced constant acceleration, (a) what acceleration did he give the ball, and (b) how much time did it take him to pitch it?

Solution 21E Step 1 : Let us consider the data given Initial velocity of the baseball v = 0 m/s i Final velocity of the baseball v = 45.0 m/s f Distance travelled by pitcher with ball d = 1.50 m
