Chloe is a champion softball batter. In a recent game, the pitcher threw the 181-g softball at Chloe and when it was 1.5 m above the ground it had a speed of 15.0 m s-1. Chloe hit the ball so hard that it cleared the outfield fence. At one point in its trajectory, the ball was 28.8 m above the ground and moving with a speed of 19.7 m/s. Calculate the work that Chloe did on the softball.
