IlI The acceleration of a baseball pitcher's hand as he delivers
a pitch is extreme. For a professional player, this acceleration
phase lasts only 50 ms, during which the ball's speed increases
from 0 to about 90 mph, or 40 m/s. What is the force of the
pitcher's hand on the 0.145 kg ball during this acceleration
phase?
