    A uniform bar of length 6a and mass 8m lies on a smooth horizontal table. Two point masses m and 2m moving in the same horizontal plane with speed 2 v and v, respectively, strike the bar [as shown in the figure] and stick to the bar after collision. Denoting angular velocity (about the centre of mass), total energy and centre of mass velocity respectively by ω , E and vc, we have after collision:

    Options :-

    1. vc = 0

    2. ω = 3v/5a

    3. ω = v/5a

    4. E = 3/5 mv2
