At a given instant, $A$ is moving with velocity of $5\,m / s$ upwards. What is velocity of $B$ at the time

Find the velocity of the hanging block if the velocities of the free ends of the rope are as indicated in the figure.

If block $A$ has a velocity of $0.6\,m / s$ to the right, determine the velocity of block $B$.

Find velocity of block ' $B$ ' at the instant shown in figure $........\,m/s$

A light string passing over a smooth light fixed pulley connects two blocks of masses $m_1$ and $m_2$. If the acceleration of the system is $g / 8$, then the ratio of masses is

Figure shows a boy on a horizontal platform $A$ on a smooth horizontal surface, holding a rope attached to a box $B$ . Boy pulls the rope with a constant force of $50\ N$ . (boy does not slip over the platform). The combined mass of platform $A$ and boy is $250\ kg$ and that of box $B$ is $500\ kg$ . The velocity of $A$ relative to the box $B$ , $5\ s$ after the boy on $A$ begins to pull the rope, will be ............ $m/s$
