Question

Jared lifts a 35.0 kg of box from the floor to a table that is 1.75 meters above the floor. How much gravitational potential energy does the box gain?

Answer 1

Given,

The mass of the box, m=35.0 kg

The height to which the box was lifted, h=1.75 m

Potential energy is the energy possessed by an object due to its position.

The gravitational potential energy gained by the box is,

`E=\text{mgh}`

Where g is the acceleration due to gravity.

On substituting the known values,

`\begin{gathered} E=35.0*9.8*1.75 \\ =600.25\text{ J} \end{gathered}`

Thus the gravitational potential energy gained by the box is 600.25 J
