Bar AB is pinned to the fixed support at A, and the collar B is pinned to the bar at its opposite end. The bar CD can slide freely through the collar at B .At the instant shown, bar AB is horizontal, ℓ = 1.2m, s = 1.07 m, θ = 60°, and ωAB = 40rad/s.

If αAB is zero at the instant shown, determine the angular velocity and angular acceleration of the bar CD.
