At what height is the potential energy of a body weighing 2 tons equal to 10 kJ.

Given:

Epotential = 10 kJ = 10 * 10 ^ 3 Joules;

m = 2 tons = 2 * 10 ^ 3 kilograms;

g = 9.8 N / kg – acceleration of gravity (constant value).

It is required to determine at what height H (meter) the body will have a potential energy equal to Epotential.

To determine the height, you need to use the following ratio:

Epotential = m * g * H, hence:

H = E potential / (m * g) = 10 * 10 ^ 3 / (2 * 10 ^ 3 * 9.8) = 10 / (2 * 9.8) = 5 / 9.8 = 0.51 meters (51 centimeter).

Answer: the body will have a potential energy of 10 kJ at a height of 0.51 meters.
