If one food Calorie equals 4184joules then how far could you go on one cream-filled cookie containing 50 calories?

Answer 1

To calculate how far you could go on one cream-filled cookie containing 50 calories, you first convert the calories to joules. 50 calories is equal to 209,200 joules (50 calories x 4184 joules). Next, you would need to know your body's energy efficiency in converting food energy to mechanical energy for movement. This efficiency can vary depending on factors such as metabolism and activity level. Ultimately, it's a complex calculation that involves various physiological and biomechanical factors.

Answer 2

The cookie contains 209200 joules of energy. This is enough to lift 21325.2 kg object one meter in the air (on earth at sea level). You could also lift a one kilogram object 21285 meters above sea level. This is found using the conservation of energy. You can't use the conventional PE = mgh for this one because the force of gravity changes with height. You have to integrate gravitational force with respect to distance, and solve for the upper limit of the integral. However, simply using the conventional PE = mgh won't make much of a difference over the course of the one meter movement. The change in the force of gravity is so small that it is negligible.
