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 93.00 mph. Assuming the ball has a mass 142.0 g 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?
