A circular plate of mass m is falling with a velocity and no angular velocity when its edge C strikes an obstruction. A line passing the origin and parallel to the line CG makes a 45° angle with the x-axis. Assuming the impact to be perfectly plastic (e = 0), determine the angular velocity of the plate immediately after the impact.
