Question

Calculate the energy of a 25 Kg object sitting on a 50 meter edge.

Answer 1

The potential energy of a body of mass $m=25kg$ elevated on the height $h = 50m$ above the ground is:

$$W = mgh = 25kg\cdot 9.81m/s^2\cdot 50m = 12262.5\space J$$

Here $g = 9.81m/s^2$ is the gravitational acceleration.

Answer. 12262.5 J.
