**1. Homework Statement**

(a) If you follow a diet of 2140 food calories per day (2140 kilocalories), what is your average power consumption in watts? (A food or "large" calorie is a unit of energy equal to 4.2*10^3 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 2140 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 61 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

**2. Homework Equations**

Power = F * v

Power = W / delta t

I know that 1 watt = 1 J/s

**3. The Attempt at a Solution**

I converted 2140 calories to Joules, which is 2140 * (4.2*10^3) = 8988000 J

I'm not sure what I need to do from there because I can't figure out the work.

Any help would be appreciated!
