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 ?
$\left( {1 + \frac{m}{M}} \right)\,v$
$\left( {1 + \frac{M}{m}} \right)\,v$
$\frac{{mV}}{{(M + m)}}$
$\frac{{MV}}{{(m + M)}}$
A man is slipping on a frictionless inclined plane and a bag falls down from the same height. Then the velocity of both is related as
For the given fig. find the speed of block $A$ when $\theta = {60^o}$
If block $A$ has a velocity of $0.6\,m / s$ to the right, determine the velocity of block $B$.
Find the velocity of the hanging block if the velocities of the free ends of the rope are as indicated in the figure.
