A mass `m` is moving at speed `v` perpendicular to a rod of length `d` and mass `M= 6m` pivots around a frictionless axle running through its centre and stickes to the end of the rod. The moment of inertia od the rod about its centre is `Md^(2)//12`. Then the angular speed of the system right after the collision us -
