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?
Homework Answers
93 mi/h.= 136.4 feet/sec
time = distance /speed = 36/136.4= 0.2639 sec
b)since time taken by batter to get the tip of bat over home plate is greater than time taken by ball to reach the home plate he does not have time to react and cant hit the ball

2. A fastball crosses the plate with a speed of 40 m/s and an angle of 5.0° relative to the horizontal. The batter hits it for a home run, launching it with 49 m/s at an angle of 35.0° to the horizontal. Mass of the baseball is 0.15 kg. a) What is the change in velocity in x-direction (Avx) and y-direction (Avy), and the change in velocity of the ball (Av)? b) What is magnitude of the impulse the baseball...

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...

A pitcher throws a 0.143-kg baseball toward the batter so that it crosses home plate horizontally and has a speed of 42 m/s just before it makes contact with the bat. The batter then hits the ball straight back at the pitcher with a speed of 51 m/s. Assume the ball travels along the same line leaving the bat as it followed before contacting the bat. (a) What is the magnitude of the impulse delivered by the bat to the...
