Laws of MotionHard
Question
System is shown in figure and wedge is moving towards left with speed 2 m/s. Then velocity of the block B will be:
Options
A.√3 m/s
B.1 m/s
C.2 m/s
D.0 m/s
Solution
l2, l3, l4, l6 are remain constant. l1 + l5 = constant so, l7 will also be constant, so, only velocity of B is along horizontal = 2 m/s.
