Acceleration Of Centre Of Mass Of System

Two block A and B of masses m and 2m respectively are connected by a spring of spring cosntant k. The masses are moving to the right with a uniform velocity v_(0) each, the heavier mass leading the lighter one. The spring is of natural length during this motion. Block B collides head on with a thrid block C of mass 2m . at rest, the collision being completely inelastic. The velocity of centre of mass of system of block A, B, & C is -
