depends on how fast its thrown. every pitcher has a different speed
A fastball is a type of pitch thrown by a pitcher.
P=mv mass=0.156 kg (5 oz troy) velocity= 144.84 m/s (90 mph) m*v=0.156kg * 144.84 m/s P=22.6kg m/s

The fastball was not invented it was just thrown and probably by the first person ever threw a baseball.
Casey Fossums eephus was clocked at 49 mph in 2006 However, he has a regular fastball. Tim Wakefield, a knuckleballer, has a fastball that hits in the high 70's. He is the slowest pitcher in Major League Baseball on a regular basis.
60mph
A bunch. In fact, the vast majority of major league pitchers have never thrown a no-hitter in major league baseball. Many more have thrown no-hitters in high school or college ball.
The speed of a fastball is dependent on the pitcher throwing the pitch. At the major league level, fastball can vary in speed by 15-20mph between different pitchers. The hardest throwers have been credited with speeds exceeding 100mph, but some pitchers can barely reach 90mph. The main difference between a fastball and other pitches is how they are thrown. A fastball is thrown similarly to the natural motion of throwing a ball, allowing the ball to roll off the fingers as it is released, imparting backspin to the ball, which provides a small amount of lift, and reduces air resistance. This lift allows the pitch to have a straighter line to the plate. The more natural motion is the primary reason for the characteristic high speed of the fastball. Curve balls are thrown with the ball rolling off the thumb, with a snap of the wrist, imparting a forward spin, causing the ball to lose lift, resulting in the characteristic "curve" of the curve ball. This motion is very unnatural, and a drop-off in speed is the result.
2010 Chapman 105 mph fastball
The fastball is the pitch most thrown and most hit in baseball.
A baseball pros fastball is on average 92 mph
Hitting a major league fast ball can be very difficult do to the fact that it is thrown at near 100 mph that makes you reaction time very limited to hit the ball its a lot harder then a lot of other sports.
