In Major League Baseball, a pitched ball has been known to hit the head of the batter (sometimes unintentionally and sometimes not). Let the pitcher be, for example, Nolan Ryan who can throw a oz baseball that crosses the plate at 100 mph. Studies have shown that the impact of a baseball with a person’s head has a duration of about 1 ms. So using Eq. (5.9) on p. 335 and assuming that the rebound speed of the ball after the collision is negligible, determine the magnitude of the average force exerted on the person’s head during the impact.
