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 ?

  • A

    $\left( {1 + \frac{m}{M}} \right)\,v$

  • B

    $\left( {1 + \frac{M}{m}} \right)\,v$

  • C

    $\frac{{mV}}{{(M + m)}}$

  • D

    $\frac{{MV}}{{(m + M)}}$
