Question

How much potential energy does a person of mass 50 kg have if they are standing at the top of a building that is 54.8 m high? Submit your answer in exponential form.

Answer 1

2.69 x 10^4 J

Explanation:

Given:

Mass (m) = 50 kg

Height (h) = 54.8 m

The potential energy is calculated by the following formula:

`E=m\cdot g\cdot h`

We replace and determine the value of the energy:

`\begin{gathered} E=50\cdot9.8\cdot54.8 \\ \\ E=26852=2.69\cdot10^4\text{ J} \end{gathered}`

The potential energy is equal to 2.69 x 10^4 joules.
