Vedclass · Answer

$P_{i}=0$

$\mathrm{P}_{f}=-\mathrm{mv}_{\mathrm{m}}+\mathrm{M} 	imes \mathrm{v}$

$	herefore \quad \mathrm{P}_{\mathrm{i}}=\mathrm{P}_{\mathrm{f}}$

$\mathrm{v}_{\mathrm{m}}=\frac{\mathrm{Mv}}{\mathrm{m}}$

$\mathrm{v}_{\mathrm{app}}=\mathrm{v}_{\mathrm{m}}+\mathrm{v}=\frac{\mathrm{Mv}}{\mathrm{m}}+\mathrm{v}$

A truck of mass $M$ is at rest on frictionless road when a monkey of mass $m$ starts moving on the truck in forward direction.If the truck recoils with a speed $v$ backward on the road, with what velocity is the monkey moving with respect to truck ?
