1. The problem statement, all variables and given/known data The oxygen taken in by the body reacts with fats, carbohydrates, and protein, liberating energy internally at a rate of about 2.180×104 J/L. If a 71.40 kg man requires 81.00 W of power even while sleeping, what is his rate of oxygen consumption? 2. Relevant equations p=fv f=mg 3. The attempt at a solution i found a value for v but iam not sure how the internal energy plays into the answer??? the value i got for v is wrong so iam not sure if i did the problem wrong or if it has to do with the other rate?
