Average power consumption from 2000 kcal diet and energy to climb Mount Everest

[mshah3]

Homework Statement

(a) If you follow a diet of 2000 food calories per day (2000 kilocalories), what is your average power consumption in watts? (A food or "large" calorie is a unit of energy equal to 4.2 103 J; a regular or "small" calorie is equal to 4.2 J.) Note for comparison that the power consumption in a table lamp is typically about 100 watts.
_______ watts
(b) How many days of a diet of 2000 large calories are equivalent to the gravitational energy change from sea level to the top of Mount Everest, 8848 m above sea level? Assume your weight is 68 kg. (The body is not anywhere near 100% efficient in converting chemical energy into change in altitude. Also note that this is in addition to your basal metabolism.)
_______days

Homework Equations

Power = Work / delta T

The Attempt at a Solution

i tried to find the power based on the calories being large and for when they are small. then i averaged the two powers. it didnt seem to work out though. =(
