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

WORK=JOULES:

Thanks:redface:

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?

Hello there! I would be happy to help you with this physics question. First, let's convert the given 500 Calories to Joules. We know that 1 Calorie is equal to 4180 Joules, so 500 Calories would be equal to 500 * 4180 = 2090000 Joules. Now, we can use the equation Work = Force * Distance to find the work done by walking up a flight of stairs. Since we know that a flight of stairs is equal to 4 meters, the distance in this case would be 4 meters. Therefore, the work done would be equal to Force * 4 meters. In order to burn all 2090000 Joules, the work done would have to be equal to 2090000 Joules. Therefore, we can set up the equation 2090000 = Force * 4, and solve for Force. Force = 2090000/4 = 522500 Newtons. Now, we can use the equation Force = Mass * Acceleration to find the mass of the person walking up the stairs. The acceleration would be equal to the acceleration due to gravity, which is 9.8 m/s^2. Therefore, we can set up the equation 522500 = Mass * 9.8, and solve for Mass. Mass = 522500/9.8 = 53367.35 kg.

Now, let's assume that the average person burns about 10 Calories per minute while walking up stairs. Therefore, in order to burn 500 Calories, it would take approximately 50 minutes of walking up stairs. So, the answer to your question would be that you would have to walk up a flight of stairs 50 times in order to burn all 500 Calories. I hope this helps! Let me know if you have any further questions.
 

1. What is the best way to approach a physics question?
