In professional baseball, pitchers can throw a fastball at a speed of 87 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? 0.2821 s you are correct. your receipt no. is 158-5539 : receipt previous tries (b) it takes (on average) 0.33 s for the batter to get the tip of his bat over home plate. how much time does that give him to react? incorrect. tries 2/5 previous tries (c) the average fast pitch in professional women’s softball is about 58 mi/h, where the regulation distance from the pitcher’s mound to home plate is 23.5 ft. how long does it take the softball to reach home plate? for simplicity, assume the pitcher releases the ball just above the center of the pitcher’s mound.
