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

A $70\mathrm{kg}$ man leaps vertically into the air from a crouching position. To take the leap the man pushes the ground with a constant force $F$ to raise himself. The center of gravity rises by $0.5\mathrm{m}$ before he leaps. After the leap the c.g. rises by another $1\mathrm{m}$. The maximum power delivered by the muscles is : (Take $\mathrm{g}=10{\mathrm{ms}}^{-2}$ )
