The hammer throw is a track-and-field event in which a 7.3-kg ball (the “hammer”), starting from rest, is

whirled around in a circle several times and released. It then moves upward on the familiar curving path

of projectile motion. In one throw, the hammer is given a speed of 29 m/s. For comparison, a .22 caliber

bullet has a mass of 2.6 g and, starting from rest, exits the barrel of a gun with a speed of 410 m/s.
