**bobpursley**, Saturday, September 27, 2008 at 6:19pmThe problem is silly, it assumes 100 percent efficiency in converting food energy to gravatational PE. On the other hand, it is going to ask you to forget about the loss of graviational PE on the trip down.

energy=2mgh

this is energy in joules, convert to calories.

Then, convert the fat protein and carbs to food calories, thence to real calories. solve for the number of bars.
