(b)Let the initial mass of body $= m$
Initial linear momentum = $mv$ &hellip;(i)
When it breaks into equal masses then one of the fragment retrace back with same velocity
 Final linear momentum = $\frac{m}{2}( - v) + \frac{m}{2}({v_2})$&hellip;(ii)
By the conservation of linear momentum
$&rArr;$$&rArr;$ $mv = \frac{{ - mv}}{2} + \frac{{m{v_2}}}{2}$$&rArr;$ ${v_2} = 3v$
i.e. other fragment moves with velocity $3v $ in forward direction
