Physics - W.E.P. Question with Solution | TestHub

The change in gravitational potential energy ($\Delta U$) of an object of mass $m$ lifted by a height $h$ near the Earth's surface is given by:$\Delta U=mgh$

Given mass $m=2\text{kg}$, height $h=5\text{m}$, and $g=10{\text{m/s}}^2$.

$\Delta U=(2\text{kg})(10{\text{m/s}}^2)(5\text{m})=100\text{J}$
