The hammer throw is a track and field event in which a 6.90-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 31.5 m/s. For comparison, a .22 caliber bullet has a mass of about 2.69 g and, starting from rest, exits the barrel of a gun with a speed of 423 m/s. Determine the work done to launch the motion of (a) the hammer and (b) the bullet.
