A baseball has mass 0.145 kilogram.
(a) If the velocity of a pitched ball has a magnitude of 46.0 m/s and the batted ball's velocity is 57.0 m/s in the opposite direction, determine the magnitude of the change in momentum of the ball and of the impulse applied to it by the bat.
kg•m/s (change in momentum)
kg•m/s (impulse)
(b) If the ball remains in contact with the bat for 2.00 millisecond, determine the magnitude of the average force applied by the bat.
