1. What is the final velocity of a hoop that rolls without slipping down a 5.00-m-high hill, starting from rest?

2.What is the efficiency of a motor that draws 1.5 KW of energy and does the equivalent work of 1.8 Hp?

3. What is the actual mechanical advantage of a system that has 20 lbs input and 220 lbs of output force?

4-5. If 220 lbs needs to be lifted 1 ft from a fulcrum or pivot point, and only 20 lbs of input force is available, how far from the fulcrum must the 20 lbs be applied? How does the distance in the second part relate to the mechanical advantage in the first part?

6. Two pulleys one of diameter 5" and the other of diameter 15" are fastened rigidly together to the same shaft, used such that the rope attached to a 100 pound load turns with the smaller pulley, while a rope is pulled to turn the larger pulley. How much force is required to lift the 100 pounds?

7. A pulley system is used such that two rope tensions are used to lift a 50 lb object, how much tension is in each rope?For every inch the object moves, the rope must move how far?

9. How much force is applied to pulling a nail with a crowbar if a the lever has 50 lbs of force applied 2 feet from pivot, and the nail is 1" from the pivot point?

10. If a ballistic pendulum weighing 22 lbs, catches a 0.4 oz bullet and it deflects upward 1 in, what was the velocity of the bullet when it hit the pendulum?

11. How fast in mph is the surface of the earth spinning?

12. For a satellite to stay over one spot on the earth at a distance of 25 miles up, how fast must it be moving? A satellite meeting this condition is said to be in what type of orbit?

13. If you drop a camera off a cliff omitting wind friction, and the cliff is 50' high, how fast will it be going in Feet per second when it hits the rocks below?
