Question
The hammer throw is a track-and-field event in which a 7.0-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 23.0 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 414 m/s. Determine the work done to launch the motion of both the hammer and the bullet.

a) hammer = 0.5 * m * v^2 = 0.5 * 7*23^2 = 1851.5 J
b) bullet = 0.5 * m * v^2 = 0.5 * 0.0026 * 414^2 = 222.8148 J
