1. How much energy is there in a 70 kg sprinter who has a linear velocity of 12.0 m/s whose center of mass is 115 cm high?

2. How much power would a defensive back need to produce to decelerate the runner from problem #1 to 0.0 m/s in 0.5 seconds? (no change in runners cm height)

3. What work is done by friction on a 30 kg crate that slides along a level surface beginning until it stops if its initial velocity was 6.0 m/s

4. Explain why the application of a large force will not ensure a large power output.

5. To compress a foam pit 0.1 meters requires 200 J of work. How much work is necessary to compress the same pit 0.4 meters? Treat the pit as a spring)

6. Use conservation of energy to determine the height from which a diver fell into the water if the speed at entry was 14 m/s.
