The hammer throw is a track and field event in which a 8.26-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 31.8 m/s. For comparison, a .22 caliber bullet has a mass of about 2.81 g and, starting from rest, exits the barrel of a gun with a speed of 404 m/s. Determine the work done to launch the motion of (a) the hammer and (b) the bullet.

Special Relativity

The theory of special relativity discusses how space and time are related to objects traveling along a straight line at a constant speed. Simply stated, as an object reaches the speed of light, its mass becomes infinite and it is unable to move faster than light. This interstellar speed limit has been the topic of much debate in astronomy, and also in science fiction when people consider how to fly over large distances.
