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 42.91 m/s (96.00 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?

131.09828 Joules

Explanation:

u = Initial velocity of the ball = 0

v = Final velocity of the ball when the batter makes contact with the ball= 42.91 m/s

m = Mass of the baseball = 0.1424 kg

Kinetic energy

The kinetic energy the ball has is 131.09828 Joules
