The mechanism shown is one of two identical mechanisms attached to the two sides of a 90-kguniform rectangular door. Edge ABC of the door is guided by wheels of negligible mass that rollin horizontal and vertical tracks. A spring of constant k = 600 N/m is attached to wheel B. Knowingthat the door is released from rest in the position θ = 30° with the spring unstretched, determinethe velocity of wheel A just as the door reaches the vertical position.
