) >) Example 5: Chapter 6, #17 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 along the curving path of a projectile. 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 grams and, starting from rest, exits the barrel of a gun with a speed of 410 m/s. Determine the work done to launch the (a) hammer and (b) the bullet. From tle work-enemy theorem.
