Physics of Baseball -- Flight Trajectories of Home Runs

University of Illinois physics professor Alan Nathan, whom I've gotten to know in recent years through the annual conferences of SABR (Society for American Baseball Research), has just posted a brief analysis of the flight trajectory of Barry Bonds's record-breaking 756th career home run. If you watch baseball games on television, from time to time you've probably heard announcers provide estimates, following a home run, of how far the ball has travelled. Professor Nathan's write-up demonstrates how such estimates can be obtained.
