A batter hits a 0.334 kg basball that was approaching him at 23.4 m/s and, as a result, the ball leaves the bat at 30.5 m/s in reverse of its original direction. the ball remains in contact with the bat for 24 ms. what is the magnitude of the average force exerted by the bat on the ball?
A baseball (m = 148 g) approaches a bat horizontally at a speed of 40.7 m/s (91.1 mi/h) and is hit straight back at a speed of 51.6 m/s (115 mi/h). If the ball is in contact with the bat for a time of 1.45 ms, what is the average force exerted on the ball by the bat? Neglect the weight of the bat, since it is so much less than the force of the bat. Choose the direction of the incoming ball as the positive direction.
