Question

 I need some assistance as to how they got their answer?

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]
