Laws of MotionHard

Question

Block B moves to the right with a constant velocity v0. The velocity of block A relative to B is :

Options

A., towards left
B., towards right
C., towards left
D., towards right

Solution


By setting string length constant
L     =   3l1 + 2l2
⇒    3v0   =   2vA
vA    = v0
vAB   =  vA − vB
          =  towards right
