The velocity of end ' $A$ ' of rigid rod placed between two smooth vertical walls moves with velocity ' $u$ ' along vertical direction. Find out the velocity of end ' $B$ ' of that rod, rod always remains in constant with the vertical walls.

A

$u \tan 2\theta$

B

$u \tan \theta$

C

$u \cot \theta$

D

$2u \tan \theta$

Solution

From constant $v \cos \theta= u \sin \theta$

$v = u \tan \theta$
