Question:

A square plate of side a and mass m supported by a ball-and-socket joint at A is rotating about the y axis with a constant angular velocity ω = ω0j when an obstruction is suddenly introduced at B in the xy plane. Assuming the impact at B is perfectly plastic (e = 0), determine immediately after impact

(a) The angular velocity of the plate,

(b) The velocity of its mass center G.
