In the given figure, if the velocity of the block C at a particular instant is - 20 m s - 1 j ^ , then the velocity of the rod (A) at that instant will be : (string is attached to wedge)

Question

In the given figure, if the velocity of the block C at a particular instant is - 20 m s - 1 j ^ , then the velocity of the rod (A) at that instant will be : (string is attached to wedge), 15 m s - 1 j ^, -15 m s - 1 j ^, 20 m s - 1 j ^, -20 m s - 1 j ^

In the given figure, if the velocity l 1 ' + l 2 ' = 0 2 0 - u = 0 u = 2 0 m s - 1 By wedge constraint u sin 3 7 ∘ = v cos 3 7 ∘ v = u × 3 4 = 1 5 m s - 1 v → = 1 5 j ^
