Answer :
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,
[tex]E=\text{mgh}[/tex]Where g is the acceleration due to gravity.
On substituting the known values,
[tex]\begin{gathered} E=35.0\times9.8\times1.75 \\ =600.25\text{ J} \end{gathered}[/tex]Thus the gravitational potential energy gained by the box is 600.25 J
