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 146-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 this maximum amount of compression is recorded as 43.1 cm. the spring\'s force constant is 817 n/m, and the position of the baseball\'s momentary rest is 7.71 m above ground level. the point in the pit where the hurler starts his pitch is 11.3 m below ground level. how much work does harold perform on the baseball? take g = 9.80 m/s2.answer in j
