The label on a candy bar says 410 Calories. For the steps and strategies involved in solving a similar problem, you may view a Video Tutor Solution. Part A Assuming a typical efficiency for energy use by the body, if a 60 kg person were to use the energy in this candy bar to climb stairs, how high could she go?

2.9174meters.

Explanation:

410Calories = 1715.44 Joules (Energy).

we have essentially calculate height at which Gravitational potential is 1715.44 Joules.

We know that Gravitational Potential as a function of height above reference point is.

.

Substituting values in gives.

in above solve for h and you will get.

h = 2.917meters (units are meters by dimentional analysis ).

That is the height a 60Kg person can reach by climbing stairs.
