a .415 kg baseball is pitched at 42 m/s. the batter hits it horizontally to the pitcher at 58 m/s.
a) find the change in momentum of the ball.
b) if the ball and bat were in contact for 4.6*10^4 s what would be the average force while they touched?

changemomentum=mass*changevelocty=
= mass*(vfvi)=mass(5842)
force*time=change of momentum
