The distance the 100kg man must climb to burn off 500 kilocalories by running up an elliptical path is 2,136.1 m.
Potential energy of the man
The potential energy of the man from a known height can be used to deternine the distance the man would have to climb.
P.E = mgh
Where;
P.E is potential energy, given as 500 kilocalories,
1 kcal = 4186.8 joules
500 kcal = 2,093,400 J
Distance traveled by the man
h = P.E/mg
h = (2,093,400) / (100 x 9.8)
h = 2,136.1 m
