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.

How much energy does a baseball that weighs 1 point 3 newtons that is thrown so that it attains a velocity of 18 meters per second possess?
Since the ball weighs 1.3 newtons on earth, its mass is (1.3/9.8) kilograms.When tossed, its kinetic energy is (1/2 m V2) = (0.5 x (1.3/9.8) x 324) = 21.49 joules (rounded)This number is only valid at the instant the ball leaves the pitcher's hand. It immediatelybegins to lose kinetic energy as air resistance slows it down, but it also gains kinetic energyas gravity accelerates it toward the ground.
