A box is suspended from a crane at a height of 32 m from the ground. The box has 7840 j of gravitational potential energy. What is the mass of the box

The mass of the box is 24.97 [kg]

Explanation:

In order to solve this problem, we must use the concept of potential energy, which is defined as the product of mass by gravity by height. So we have the following equation.

where:

Ep = potential energy [J]

m = mass [kg]

g = gravity acceleration = 9.81 [m/s^2]

h = elevation = 32 [m]

7840 = m*9.81*32

m = 24.97 [kg]
