Find the potential energy of the object. The potential energy of a mass ‘m’ at the height ‘ h’ is given by, P = m.g.h Given: m = 5kg and g = 10 m/s 2 and h = 100m. Aim: Find the potential energy. Plugging in the values in the formula. P = m.g.h ⇒ P = (5)(10)(100) ⇒ P = 5000J Thus, the potential energy of the object is 5000J.
