If block $A$ has a velocity of $0.6\,m / s$ to the right, determine the velocity of block $B$.
$0.6\,m / s$ in upward direction
$0.6\,m / s$ in downward direction
$1.8\,m / s$ in upward direction
$1.8\,m / s$ in downward direction
The velocities of $A$ and $B$ are marked in the figure. The velocity of block $C$ is ......... $m/s$ (assume that the pulleys are ideal and string inextensible)
In the arrangement shown in fig. the ends $P$ and $Q$ of an unstretchable string move downwards with uniform speed $U$. Pulleys $A$ and $B$ are fixed. Mass $M$ moves upwards with a speed.
Acceleration of system is :-
The pulleys in the diagram are all smooth and light. The acceleration of $A$ is a upwards and the acceleration of $C$ is $f$ downwards. The acceleration of $B$ is
