What is the gravitational potential energy of a clock that has a mass of 4.0 kg and is positioned 1.5 m off the ground?

Respuesta :

The potential energy is the mass multiplied by the height multiplied by the earth accelerations
Ep = mgh
in your case 

Ep = 4kg * 9.8m/s^2 * 1.5m = 59J

Answer:

59J
