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
[tex]GPE=m\cdot g\cdot h[/tex]
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
[tex]\begin{gathered} GPE=28.665\cdot9.8\cdot18 \\ GPE=5056.506\;J \end{gathered}[/tex]
Therefore, the gravitational potential energy of the object is 5056.506 J
Option E is the correct answer.
