If it was simply a question of momentum then the answer would be m1v12 = m2v22 Where m1 = initial mass of the ship m2 = final mass of the ship v1 = initial velocity v2 = final velocity However, moduals do not simply stop existing. They have some momentum of their own that they keep and they have an ejection force of 10. I would assume that the ejection force pushes the two parts away from each other with equal force in either direction which would lead to 5 units of acceleration for the remaining ship. So I think that the final speed of the ship would be v1 + 5x And the final speed of the decoupler would be v1 - 5x Where x is the unknown acceleration from the ejection on the part of the ship it's attached to.
