What is the potential energy of a 2 kg mass at a height of 40 meters?

The potential energy of a 2 kg mass at a height of 40 meters is 784 J

Explanation:

Potential energy is that energy that a body possesses due to the height at which it is located and whose unit of measurement of the International System of Units is the joule (J).

The potential energy of a body is the result of multiplying its mass by its height and by gravity:

Ep=m*g*h

Potential energy Ep, is measured in joules (J), mass m is measured in kilograms (kg), gravity, g, in meters / second-squared (), and height, h , in meters (m).

In this case:

Replacing:

Ep= 2 kg* 9.8 * 40 m

Solving:

Ep= 784 J

The potential energy of a 2 kg mass at a height of 40 meters is 784 J

explanation:

newton's third law, for every action there is an equal and opposite reaction.
