1. The problem statement, all variables and given/known data

An object of mass 2.00 kg is held at a position A, a vertical height of 20.0 m above the ground. Point B is 8.00 m directly below A. Neglect air resistance and use g=10.0 m/s(squared)

What is the ratio of the total energy of the object at position A to position B?
2. Relevant equations

g=10.0 m/s(squared)

3. The attempt at a solution

What is the difference in energy between the object at rest at position A and the object at rest at position B? (There's another equation you need, and you must have just seen it if you've been assigned this problem.)

By the way - did you quote the problem exactly? I ask because it doesn't actually state how the object gets from A to B. If it's just dropped and is moving when it passes B, that's different than if you just lower it to B and let it come to rest there.
