$15\,\, m/s \downarrow $
$15 \,\,m/s \uparrow$
$5\,\, m/s \downarrow $
$5 \,\,m/s \uparrow $
Find the velocity of the hanging block if the velocities of the free ends of the rope are as indicated in the figure.
If pulleys shown in the diagram are smooth and massless and $a_1$ and $a_2$ are acceleration of blocks of mass $4 \,kg$ and $8 \,kg$ respectively, then
For the given fig. find the speed of block $A$ when $\theta = {60^o}$
