Answer:
Step-by-step explanation:
It is not possible to determine the magnitude of the average force exerted by the bat on the ball with the information given. The time that the bat is in contact with the ball, 1.4 ms, is not enough to determine the force. The force exerted by the bat on the ball depends on various factors, including the mass of the bat, the mass of the ball, the velocity of the bat and the ball before and after the collision, the impact point on the bat, and the material properties of the bat and the ball. In order to calculate the force exerted by the bat on the ball, you would need to know at least some of these additional variables.
