While being thrown, a net force of 132 N acts on a baseball (mass = 140g) for a period of 4.5 x 10-2 sec. [Hint: Convert mass to kg]

A.) What is the magnitude of the change in momentum of the ball?

B.) If the initial speed of the baseball is vi=0.0 m/s, what will it’s speed be when it leaves the pitchers hand?

C.) When the batter hits the ball, a net force of 1320 N, opposite to direction of the balls initial motion, acts on the ball for 9.0x10^-3 seconds during the hit. What is the change in momentum of the ball?

D.) What is the final velocity of the ball?

E.) What force does the ball exert on the bat in the question above? Explain.
