An isolated system is made by two bodies of mass \(m_{1}=12.0 \mathrm{~kg}\) and \(m_{2}=2.0 \mathrm{~kg}\). They are initially in equilibrium and are separated by a distance \(d=1.23 \mathrm{~cm}\), attracting one another with a force of constant magnitude equal to \(F=0.21 \mathrm{~N}\) and direction connecting the two bodies. What is the velocity of the center of mass of the system? If we place the origin at the initial position of \(m_{1}\), at which distance the two bodies collide?
