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 2v and v, respectively, strike the bar [as shown in the fig.] and stick to the bar after collision. Denoting angular velocity (about the centre of mass), total energy and centre of mass velocity by w, E and vc respectively, we have after collision
  • a)
    vc = 0

Applying conservation of linear momentum 2m (– v) + m (2v) + 8m × 0 = (2m + m + 8m) vc
⇒ vc = 0
Applying conservation of angular momentum about centre of mass
