Question #18193

A baseball of mass 0.143kg is thrown at a speed of 68m/s.

1. What is the kinetic energy of the baseball?

2. If the ball is released from a height of 2.5m, what is it's potential energy?

3. What is the ball's total energy?

4. If the batter hits the ball with a speed if 61m/s, what is the ball's kinetic energy at the time of impact?

5. If the ball was hit at a height of 0.6m, what is the ball's potential energy at the time of impact?

6. What is the ball's total energy at the time of impact?

Bonus: How much energy did the bat transmit to the ball? (Note: if the bat gave energy to the ball, then this is a positive number. If the bat absorbed energy from the ball, then this is a negative number.)
