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

A gardener pushes a lawn roller through a distance $20\mathrm{m}$. If he applies a force of $30\mathrm{kg}-\mathrm{wt}$ in a direction inclined at $60^{\circ }$ to the ground, the work done by the gardener in pushing the roller is $$\left[\mathrm{g}=9.8\mathrm{m}/{\mathrm{s}}^2,\sin 30^{\circ }=\cos 60^{\circ }=\frac{1}{2},\cos 30^{\circ }=\sin 60^{\circ }=\frac{\sqrt{3}}{2}\right]$$
