Question

Calculate the gravitational potential energy of a 10 kg box on the top shelf of a closet 2.6 m above the floor .

Answer 1

255.06 joules

Explanation:

We have that the potential energy is given as follows:

`PE=m\cdot g\cdot h`

where m is the mass, g is the gravity and h is the height, we replace and we would have:

`\begin{gathered} PE=10\text{ kg}\cdot9.81(m)/(s^2)\cdot2.6\text{ m} \\ PE=255.06\text{ J} \end{gathered}`

potential energy equals 255.06 joules
