Detailed Solution

Let the initial mass of body = m Initial linear momentum = mv --------(i)When it breaks into equal masses then one of the fragment retrace back with same velocity ∴ Final linear momentum =m2(-v)+m2v2---------------(ii)By the conservation of linear momentum ⇒mv=-mv2+mv22⇒v2=3vi.e. other fragment moves with velocity 3v in forward direction
