2.21 • 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 con-
stant acceleration, (a) what acceleration did he give the ball, and
(b) how much time did it take him to pitch it?
[675 m/s^2; (b) 0.0667 s]

Expert Solution

Step 1

Equation of motion are

v = u + at;

s = ut + (1/2) at²
