Question

In the figure, the blocks are of
equal masses. the pulley is fixed. In
the position shown. A moves down with a
Speed u, VB = the speed of B.​

Answer 1

Answer:

Let the velocity of the block B be v

b

along horizontal

The speed of the rope is u along the axis joining block and pulley

Taking the horizontal component of speed u of rope along horizontal, we get ucosθ=v

b
