Calculate how much kinetic energy does the ball have

Reference no: EM13336906

Professional baseball pitchers can deliver a pitch which 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 42.46 m/s (95.00 mph). Assuming the ball has a mass 0.1440 kg and has this speed just before a batter would make contact, how much kinetic energy does the ball have?

How high would the ball need to be dropped from to attain the same energy (neglect air resistance)? (The acceleration due to gravity is 9.81 m/s2.)
