physics

the instant before a batter hits a 0.14 kilogram baseball, the velocity of the ball is 45 m/s west. the instant after the batter hits the ball, the ball's velocity is 35 m/s. The bat and ball are in contact for 1.0*10^-2.
1. determine the magnitude and direction of the average acceleration of the ball in contact with the bat.
2. calculate the magnitude of the average force the bat exerts on the ball while they are in contact.
