Compute the answer of the following 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 147-g 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 the maximum amount of compression is recorded as 47.1 cm. The spring's force constant is 809 N/m, and the position of the baseball's momentary rest is 7.11 m above ground level. The point in the pit where the Hurler starts his pitch is 14.7 below ground level.

Part 1- How much does Harold perform on the baseball? Take g = 9.80 m/s².

You need help to compute the above problem.
