3. The SI unit in which K.E. is often measured is the ____________.
4. Rodger Maris swung a bat which had a mass of 2 Kg at a velocity of 45 m/s. How many joules of kinetic energy could he give to a ball?

5. Barry Bonds swings a bat which has a mass of 1.5 Kg at a velocity of 55 m/s. How many joules of kinetic energy could he give to a ball?

6. Which is more important to hitting a home run - a heavier bat or a faster swing?

7. A golf pro swings his driver which weighs 0.75 kg at a velocity of 60 m/s. Calculate the kinetic energy of the club.

8. Calculate the K.E. of a car which has a mass of 1000 kg and is moving at the rate of 20 m/s.

9. What is the K.E. of a soccer ball which has a mass of 0.8 kg and is kicked at a velocity of 10 m/s?

10. Calculate the K.E. of a running back that has a mass of 80 kg and is running at a velocity of 8 m/s.
