The collars are pin connected at B and are free to move along rod OA and the curved guide OC having the shape of a cardioid, r=[0.2(1+cosθ)] m. At θ = 33 ∘, the angular velocity of OA is θ˙=3.0 rad/s. (Figure 1) Determine the magnitude of the velocity of the collars at this point. Express your answer to three significant figures and include the appropriate units
