Solve the given problem:

Problem: Harold the Hurler is a physics student who is renowned for his baseball pitching arm. In order to determine the amount of work he performs in throwing a baseball, Harold devises an experiment. He stands at the bottom of a deep pit and hurls a 0.147-kg baseball through an open third-floor window in a nearby building. Harold\'s aim is so accurate that the ball then smoothly enters the tube of the Baseball Absorber that Harold invented and patented. In this device the ball compresses a spring until it comes momentarily to rest, and this maximum amount of compression is recorded as 0.451 m. The spring\'s force constant is 847 N/m, and the position of the baseball\'s momentary rest is 7.49 m above ground level. The point in the pit where the Hurler starts his pitch is 13.5 m below ground level.

Part A: How much work does Harold perform on the baseball?

I want help to find how much work does Harold perform on the baseball and take g = 9.80 m/s².
