Converting the energy of one food calorie into mechanical energy, how high could you lift a 196-lbs person?
Homework Answers
E = 1cal = 4.12 J, m = 196 lbs =88.9 kg
From conservation of energy
E = U+K
E = mgh +0
4.2 = (88.9*9.8)h
h = 0.0048 m

3) In this problem, you will use the relationship between the Joule (mechanical energy), the calorie (heat energy), and the Calorie (food energy). The relationship between the three is: 4,186 Joules = 1,000 heat calories = 1 food Calorie. 4,186] = 1,000 cal = 1 Cal. conversions, calculate how many times (and how many flights of steps) a 150 Ib person would have to climb the Sears Tower located in downtown Chicago if they ate a 500 Cal piece of...

9) In chis problem, you will use the relationship between the Joule (mechanical energy), the calorie (heat energy), and the Calorie (food energy). The relationship between the three is: 4,186 Joules 1,000 heat calories 1 food Calorie. 4,186]= 1,000 cal=1 Cal. Using the above conversions, calculate how many times (and how many flights of steps) a 150 Ib person would have to climb the Sears Tower located in downtown Chicago if they ate a 500 Cal piece of apple pie...

A food Calorie is a unit of energy equal to about 4184J. When you consume a 100 Calorie doughnut, that energy is stored in your body unless you use it (conservation of energy, folks). (a) How much work do you do when you lift yourself (assume m “ 80kg) up one stair? Note: The typical stair in the US is about 18cm. (b) How many times do you need to walk up the Exorcist stairs (about 80 stairs) to work...

A. Food Energy. Energy is stored in food as the potential energy of the electrical bonds in molecules. Your body converts food energy to mechanical energy and heat. Food energy is expressed in “calories”, which are actually kilocalories (kcal, with 1 kcal= 4.185 kJ) How many joules are in a 130-kcal serving of breakfast cereal? B.
