two identical ships launch on parallel paths r distance apart. the are completely alone [nothing to affect them gravitationally [but themselves]]. once they reach some velocity v [they both reach the same velocity at the same time [everything is identical]] they turn off their engines and coast.
can someone on a ship determine the velocity v by measuring the decreasing distance between the two ships over time? [i.e. the faster they go, the more mass they have and the more they should be attracted to each other?]
