Question

Choose the best answer1. An object of mass 28.665 kg is located at the topof a 18 m tall building. Calculate thegravitational potential energy of the objectwith respect to the ground. (1 point)A. O795.673 JB.3844.662 JC. 03127.314 JD. 08356.675 JE.5056.506 J

Answer 1

We are given the following information.

Mass of object = 28.665 kg

Height of building = 18 m

We are asked to calculate the gravitational potential energy of the object.

Recall that the gravitational potential energy is given by

`GPE=m\cdot g\cdot h`

Where m is the mass, h is the height, and g is the acceleration due to gravity.

g = 9.8 m/s^2

Let us substitute the known values into the above formula

`\begin{gathered} GPE=28.665\cdot9.8\cdot18 \\ GPE=5056.506\;J \end{gathered}`

Therefore, the gravitational potential energy of the object is 5056.506 J

Option E is the correct answer.
