Q1. A baseball (m = 149 g) approaches a bat horizontally at a speed of 40.20 m/s (90 mi/h) and is hit straight back at a speed of 47.80 m/s (107 mi/h). If the ball is in contact with the bat for a time of 1.10 ms, what is the average force exerted on the ball by the bat? Neglect the weight of the ball, because it is so much less than the force of the bat. Desire the direction of the incoming ball as the positive direction.
