draw the fbd of the system , write eqn of motion and obtain the acceleration of the bodies

let us assumw it comes out as a 

now acceleration of the centre of mass will be given by 

                                                                          = (m1a-m2a)/(m1+m2)

negative sign because of the oppositedly directed accn of the two bodies
