Help Solve Human Energy Problem - 50 kg Hiker Climbs 1000m Mountain

In summary, a hiker weighing 50 kg climbed a 1000m mountain in 3 hours. The average O2 consumption during the climb was 2x10^-3 m^3/min, equivalent to an energy expenditure of 4x10^4J/min. The remaining energy not used to overcome potential energy would appear as heat in the body.

human energy problem!

okay...i have this assignment that's due tomorrow morning so I'm begging for some help. There is only one problem that I'm totally lost on.

A 50 kg hiker climbs a mountain 1000m high in 3 hrs. Assuming the average O2 consumption during his climb was 2x10^-3 m^3/min(2 liters/min) corresponding to an energy expenditure of 4x10^4J/min, how much energy appears as heat in the body?

:cry:
Any help would be great...Thanks so much! :smile:

Calculate the total energy expenditure (Rate * climb time)

How much of this is used to overcome the potantial energy?

How much is left? What ever left should appear as heat in the body.
