Problem
A baseball of mass 0.145kg is pitched horizontally toward a batter at 40ms−1. After being struck by the bat, the ball travels in the opposite direction at 50ms−1. The ball is in contact with the bat for 1.6ms. Air resistance is negligible, and the magnitude of the ball’s speed is constant immediately before and after contact.
(a) Determine the magnitude of the impulse delivered to the baseball during its interaction with the bat.
(b) Calculate the magnitude of the average force exerted on the baseball by the bat during the collision. Express your answer with appropriate units.
