Two identical particles move towards each other with velocity 2v and v, respectively. The velocity of the centre of mass is:

Two bodies of masses 4kg and 2kg are moving towards each other with 3ms and 2ms! respectively. Then velocity of centre of mass

Two particles initially at rest move towards each other due to internal forces. Find the velocity of centre of mass when velocity of one particle is v and that of the other is 2v
