A baseball with a mass of 154 g is thrown horizontally with a speed of 38.9 m/s (87 mi/h) at a bat. The ball is in contact with the bat for 1.20 ms and then travels straight back at a speed of 45.0 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.) N
