Homework 2.21 - A Fast Pitch. The fastest measured pitched baseball left the pitcher's hand at a speed of \( 45.0 \mathrm{~m} / \mathrm{s} \). If the pilcher was in contact with the ball over a distance of \( 1.50 \mathrm{~m} \) and produced constant acceleration, (a) what acceleration did he give the ball, and (b) how much time did it take him to pitch it?

Step 1
0 m/s, the initial velocity (u) is 0 (as the ball starts from rest), and the distance (s) over which the acceleration occurs is 1.50 m. We can use the equation of motion v^2 = u^2 + 2as to find the acceleration (a). Substituting the known values, we get: 45.0^2 = Show more…

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