∙ 14y agoWhen the ball is released, its kinetic energy is ( 1/2 m v2 ) = (1/2) (.25) (50)2 = (0.5) (.25) (2500) = 312.5 J.That's the energy put into the ball's motion by the pitcher. As the ball travels from the mound to the plate, there is no horizontal component of work other than the work done to move air out of its way horizontally. In the vertical direction, besides moving air, the only other work is that done by gravity. Its magnitude is (weight of the ball) x (distance the ball sinks).

How much force ( in newtons ) does a baseball pitcher have to exert on a 250g baseball to make it accelerate to 50 ms the instant that leaves his hand?

How much force in Newtons does a baseball pitcher have to exert on a 250 g baseball to make it accelerate to 50 miles per second the instant that it leaves his hand?
Force = mass x acceleration Therefore you need to know what time it takes to accelerate the 250 gramme ball from zero to 50 miles per second. ( 50 mi/s is supersonic, did you mean 50mph?) Acceleration = (final velocity - initial velocity) divided by time. Therefore a = (80 467.2 m.s-1 - 0) / t seconds. Therefore force (Newtons) = 0.25 kilogramme x 80 467.2 m.s-1 / t seconds. (80 467.2 metres per second = 50 miles per second) (no baseball pitcher can ever achieve that, by the way).
What is pitch time?
In baseball, the time of pitch is that instant when the pitcher has begun his pitching motion and, by the rules, has committed himself to throwing the pitch. This instant thus occurs before the pitcher actually releases the ball. Once a pitcher commits himself to throwing a pitch, it is illegal for him to return to his set. If that happens, he is charged with a balk, and any baserunners are allowed to advance a base. A baserunner's time-of-pitch base is the base which he has last legally reached at the time of pitch.
