Default Are the relative speeds of two moving bodies symmetric?

Let two bodies, A and B, with equal masses, move inertially
along a straight line. Velocity of A wrt B is V_ab, and velocity
of B wrt A is V_ba. Since both bodies are inertially moving
along a straight line, we assume V_ab = - V_ba will always
hold, so we say both velocities are symmetrical. Suppose
now, body A accelerates during a time t at constant a_A along
the same straight line to yield a final velocity V_ab'. Can we
still claim the new velocity of B wrt A is V_ba' = -V_ab'? IOW,
isn't it reasonable to claim that the new V_ba' is actually not
that new, but V_ba' = - k*V_ab', for a real k 1? If it is true
that
V_ba' = - k*V_ab', for a real k 1, after the acceleration a_A
and V_ab' V_ab, then, can we conclusively say that
acceleration a_A has created an eventual gravitational field,
by claiming that both masses are no longer equal?


"Hey, ****ing moron, you can't even trolling!
I'll teach you how to troll in this NG. Find
some flaws in a well-established theory.
Once, you have convinced all of us those
flaws are real inconsistencies, then we'll let
you propose a new theory which can repair
those flaws. Then, and only then, we will
discuss about your 'wonderful theory'. And then,
all we'll see the great troll you can be. Until
then, **** off, moron! "

Deer Mike:
Are you one of those shrunken heads needing to call how
idiotic are the others in order to forget the irreparable
idiocy that resides in you?- Hide quoted text -

I just quoted you troll. Don't you recognize your own statements?

Then, stop quoting me. Quote your own statements, troll.- Hide quoted text -
