A 0.145 kg baseball is pitched at 42 m/s. The batter hits it horizontally to the pitcher at 58 m/s.

GIVEN:

m = 0.145 kg

v = 42 m/s

batter v = 58 m/s

a. Find the change in momentum of the ball.

p = mv

p = (0.145)(42)

p = 6.09

--> What velocity would I use? Would i use the velocity of the baseball

b. If the ball and bat are in contact for 4.6 x 10^-4 s, what is the average force during contact?
