A circular hoop of mass m and radius R rests flat on a horizontal frictionless surface. A bullet, also a mass m and moving with velocity v, strikes the hoop and gets embedded in it. The thickness of the hoop is much smaller than R. The angular velocity with which the system rotates after the bullet strikes the hoop is:
