So... same result no algebra.

That works if the DMs are fairly close. If we are talking say a cycle (1/3 DM) and a loaded Semi (19DM), well if the cycle rear ends the semi, the semi hardly notices as even flattened against the rear the cycle lacks the relative mass to move the semi appreciably. The Semi rear ending the cycle, well won't be slowed enough to matter, same deal.
