Asquare 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 to be perfectly plastic (e = 0), identify the expressions for the kinetic energy lost when the plate hits the obstruction at b.
