A- If the velocity of a pitched ball has a magnitude of 35.0 m/s and the batted ball's velocity is 65.0 m/s in the opposite direction, find the magnitude of the change in momentum of the ball.
B- Find the magnitude of the impulse applied to it by the bat.
C- If the ball remains in contact with the bat for 2.00 ms, find the magnitude of the average force applied by the bat.
