A particle of mass m is moving horizontally at speed v perpendicular to a uniform rod of length d and mass M = 6m . The rod is hinged at centre O and can freely rotate in horizontal plane about a fixed vertical axis passing through its centre O. The hinge is frictionless.The particle strikes and sticks to the end of the rod. The angular speed of the system just after the collision :
