343m/s x 5.71s = 1958.53m, less the distance from the level of the hole's opening to the spelunder's ear.

How do you measure a dropped ball's potential energy?
When a ball is dropped, it no longer has potential energy. Before it drops, you can calculate the potential energy (= mgh); to actually measure this, you would have to measure the force, and multiply that by the distance.
When somthing drops what type of energy conversion is taking place?
When a object is dropped downward from rest, the gravitational potential energy is converted to kinetic energy.
What energy does a waterfall transfer?
This is one of the most worstly worded questions i have ever heard in my entire life. ++ That answer's no advertisement for good grammar either! :-) The water above the fall has potential mechanical energy which converts to kinetic energy as the water drops. On striking the rock or water at the bottom, a lot of that energy is dissipated as sound and heat (though you may not think the latter if you've bathed in a river!).

Where does the water in a waterfall have the most gravitational potential energy?
The water above receives energy as it falls down the short waterfall. This energy was stored as potential energy in the gravitational field of the Earth and came out of storage as the water dropped. This energy which came out of the gravitational field ended up being expressed as the kinetic energy of the water. That is, the water gains kinetic energy as it drops. An ounce of water is going faster when it hits the bottom of the waterfall than it was when it went over the top of the waterfall.
