Chapter 4, Problem 37P
|| BIO Human biomechanics. The fastest pitched baseball was measured at 46 m/s. Typically a baseball has a mass of 145 g. If the pitcher exerted his force (assumed to be horizontal and constant) over a distance of 1.0 m, (a) what force did he produce on the ball during this record-setting pitch? (b) Make free-body diagrams of the ball during the pitch and just after it has left the pitcher’s hand.
