Solve the all parts of given problem:

Problem: The hammer throw is a track and field event in which a 8.49-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 26.6 m/s. For comparison, a .22 caliber bullet has a mass of about 2.85 g and, starting from rest, exits the barrel of a gun with a speed of 413 m/s.

Part A: Determine the work done to launch the motion of the hammer?

Part B: Determine the work done to launch the motion of the bullet?

I need help to find the work done to launch the motion of the hammer.
