Passage-I : A rod AB length 2m and mass 2kg is lying on a smooth horizontal x-y plane with its centre at origin O as shown in figure. An impulse J of magnitude 10Ns is applied perpendicular to AB at end A. If the rod is hinged at B and instead of impulse J, a point masses of 1 kg moving with a speed 10m/s collides at A and sticks to it, then find angular velocity of the rod just after the collision
