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. Determine the work done to launch the motion of
(a) the hammer and
(b) the bullet.
