Professional baseball pitchers deliver pitches that can reach the blazing speed of 100 mph (miles per hour). A local team has drafted an up-and-coming, left-handed pitcher who can consistently pitch at 43.58 m/s ( 97.50 mph ) . Assuming a pitched ball has a mass of 0.1424 kg and has this speed just before a batter makes contact with it, how much kinetic energy does the ball have? K ball = 135.224 J Recall that the acceleration due to gravity is 9.81 m/s 2 . How high would the ball need to be dropped from to attain the same energy as it did when it was pitched (neglect air resistance)
