Professional baseball pitchers can deliver a pitch that can reach the blazing speed of 100 mph (miles per hour)
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 99.00 mph. Assuming the ball has a mass of 142.8 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/s?.
hball = _______ m

In professional baseball, pitchers can throw a fastball at a speed of 93 mi/h. (a) Given that the regulation distance from the pitcher’s mound to home plate is 36 ft, how long does it take the ball to reach home plate after the ball leaves the pitcher’s hand? 0.2639 s (b) It takes (on average) 0.29 s for the batter to get the tip of his bat over home plate. How much time does that give him to react?

1. In Major League Baseball, a typical fastball is pitched at a speed of about 90 mph, or 40 m/s. The batter can perform the remarkable task of completely reversing the direction of this ball and sending it back at about 105 mph, or 47 m/s. Doing this at just the right millisecond to get the ball to go where the batter wants it to go is such an amazing feat that a Yale physicist once jokingly declared that hitting...
