A circular hoop of mass m and radius R rests flat on a horizontalfrictionless surface. A bullet, also of mass m, and moving with avelocity v, strikes the hoop and gets embedded in it. The thicknessof the hoop is much smaller than R. The angular velocity withwhich the system rotates after the bullet strikes the hoop is(B4R2V3R3Re)4R
