Assuming 100% of your energy can be converted to electrical power, and electricity costs $0.10 for 1 kilowatthour, how high should you climb to make one penny's worth of electricity? Show all work & units.
I have 288.8 watts, and that's as far as I have been able to reach.

so you want to climb the quivelant of 10 cents.
10kw*hr=10kw*3600sec=3.6E4joules
3.6E4joules=mgh
So you have to put your weight (mg, in Newtons) and solve for h
Hint: 1N =.225 lb (force)
so if I weigh 150 lbs, then weight in newtons is 150/.225=667N
3.6E4=667N*h
h=54m
check all that. 
It actually wants to find how far you could climb with a penny.
