Professional baseball pitchers can deliver a pitch 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 throw at 92.50 mph. Assuming the ball has a mass of 143.4 g and has this speed just before a batter would make contact, how much kinetic energy does the ball have? Kball = From what height would the ball need to be dropped to attain the same energy, neglecting air resistance? The acceleration due to gravity is 9.81 m/s2. E hball =
