A batter swings at a baseball (mass $0.145 \mathrm{~kg}$ ) that is moving horizontally toward him at a speed of $40.0 \mathrm{~m} / \mathrm{s} .$ He hits a line drive with the ball moving away from him horizontally at $50.0 \mathrm{~m} / \mathrm{s}$ just after it leaves the bat. If the bat and ball are in contact for $8.00 \mathrm{~ms}$, what is the average force that the bat applies to the ball?

Key Concepts

Momentum

Momentum is a physical quantity defined as the product of an object's mass and its velocity. It is a vector quantity, meaning it has both a magnitude and a direction. Understanding momentum is essential in problems involving collisions and interactions, as it helps analyze how objects move before and after an event.

Impulse

Impulse is defined as the product of the average force applied to an object and the time duration over which this force acts. It represents the change in momentum of the object as a result of the force. This concept allows us to link the force experienced by an object to the resulting alteration in its motion.

Impulse-Momentum Theorem

The impulse-momentum theorem states that the impulse acting on an object is equal to the change in its momentum. This theorem provides a useful framework for solving problems where forces are applied over brief time intervals, such as in collisions or rapid impacts, by connecting the applied force, duration, and the corresponding change in momentum.
