The distance of a fastball's travel is calculated using the equation D = V0t + ½at2, where D is the distance, V0 is the initial velocity, t is the time, and a is the acceleration due to gravity.
The average speed of a fastball is around 90 mph (miles per hour). However, this can vary depending on the pitcher and the specific pitch.
The average distance a professional pitcher can throw a fastball is around 60 feet and 6 inches, which is the distance between the pitching mound and home plate in baseball.
Some factors that can affect the distance a fastball travels include the pitcher's strength and technique, the type of pitch thrown, the air density and temperature, and the wind speed and direction.
The speed of a fastball directly affects its distance. The faster the pitch, the farther it will travel due to the increased force and momentum behind the ball.
