Question 1040713: 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 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 starts at zero and accelerates to 45 m/sec --> avg speed = 22.5 m/sec
-----
t = d/r = 1.5/22.5 = 1/15 second
========
Acceleration = 45 m/sec/(1/15 sec) = 675 m/sec/sec
