A 0.050 kg whiffle ball is thrown horizontally toward a batter at 12.3 m/s. The batter swings the bat and hits the ball, applying an average force of 15.714 N to the ball, causing the ball to head back in the opposite direction (away from the batter) at 9.70 m/s. (assuming that away from the batter is the positive x-direction, determine the time that the bat and ball were in contact.

A baseball with a mass of 150 g is thrown horizontally with a speed of 40.1 m/s (90 mi/h) at a bat. The ball is in contact with the bat for 1.00 ms and then travels straight back at a speed of 45.2 m/s (101 mi/h). Determine the average force (in N) exerted on the ball by the bat. Neglect the weight of the ball (it is much smaller than the force of the bat) and choose the direction of the incoming ball to be positive. (Indicate the direction with the sign of your answer.)
