Need help with physics question

  1. Oct 31, 2005 #1
    Can anyone help me figure out this question?
    If you have just consumed 500 Calories of food, how many times do you have to walk up a flight of stairs in order to burn all the Calories?

    A flight of stairs is = to 4 meters
    500 Calories * 4180 Joules = 2090000 Joules

    Note that we have a homework help forum for this type of question.

    You have found the number of Joules contained in 500 kcals of food. Now you just need to compute that to how high you can lift your body with that amount of Joules. What formulas do you have for work?
