Question

A .0100-kilogram grape hangs from a vine 1.50 meters from the ground. What is the potential energy of the grape?

Answer 1

The potential energy of the grape is `1.47xx10^(-1)J`"

Explanation:

We have to use the following equation to calculate the potential energy:

Let's identify our known and unknown variables:

`color(green)("Knowns:")`

• Mass, height, and the acceleration due to gravity.

`color(red)("Unknowns:")`

• Potential energy

All we have to do is plug our known values into the equation like this:

`0.0100kgxx9.81m/s^(2)xx1.50m` `=` `1.47xx10^(-1)J`

`color(orange)("Note:`

Therefore, the potential energy is `1.47xx10^(-1)J`
