For the plate of Prob. 18.29, determine (a) the velocity of its mass center G immediately after the impact, (b) the impulse exerted on the plate by the obstruction during the impact.

Prob. 18.29

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.
