Reference no: EM13531289

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 92.00 mph. Assuming the ball has a mass 144.0 g and has this speed just before a batter would make contact,
