## A batter bunts a pitched baseball, blocking the ball without swinging, (a) Can the baseball deliver more kinetic energy to the bat and batter than the ball carries initially? (b) Can the baseball deliver more momentum to the bat and batter than the ball carries initially? Explain each of your answers.

Expert Solution

(a)

To determine
The kinetic energy given to the bat.

### Explanation of Solution

From Law of conservation of energy, energy can neither be created nor destroyed, but can only be transferred from one form to other.

If the kinetic energy delivered to the bat exceeds the initial energy carried by the ball, then the law of conservation of energy is violated.

Conclusion:

No. It is not possible to deliver greater kinetic energy to the bat.

Expert Solution

(b)

To determine
The momentum to the bat.

### Explanation of Solution

The momentum delivered by the ball will be greater since it bounces off the bat after colliding with it.

Conclusion:

Yes. It is possible to deliver greater momentum to the bat
