At what height is a body weighing 250 kg if its potential energy is 1.5 kJ?

m = 250 kg.

g = 10 N / kg.

Ep = 1.5 kJ = 1500 J.

h -?

The potential energy of a body Ep of mass m, which is at a height h above the earth’s surface, is determined by the formula: Ep = m * g * h, where g is the acceleration of gravity.

The acceleration due to gravity on the earth’s surface is g = 10 N / kg.

The height h at which the body is located can be expressed by the formula: h = En / m * g.

h = 1500 J / 250 kg * 10 N / kg = 0.6 m.

Answer: the body is at a height of h = 0.6 m above the earth’s surface.
