Two objects of masses m1 = 200 gm and m2 = 500gm possess velocities  just prior to a collision during which they become permanently attached to each other.
  • a)
    They velocity of centre of mass is 
  • b)
    The final momentum of the combination in the laboratory frame is 
  • c)
    The fraction of the initial total kinetic energy is associated with the motion after collision is 0.5.
  • d)
    The fraction of the initial total kinetic energy is associated with the motion after collision is 0.72.
Correct answer is option 'A,B,D'. Can you explain this answer?

(b) Final momentum =  (m1+m2) V = 0.7V =

Now applying the law of conservation of momentum

where v is the velocity of the combined particle in the laboratory system. Note that v is identical to V, i.e.,   
Therefore
