Marc’s observation: (“. . . the definitions of the two objects are
mutually exclusive. “)
is interesting, and just the opposite of the thinking in my recent post on
this thread =>
Regarding their kinetic behavior in the simplified collision which I
considered, I used an infinitely massive
point object to be each : the unstoppable object and the immovable object.
So in my model they are far from mutually exclusive - they are identical :-)
As infinitly massive point objects with no other intrinsic properties, they
are indistinguishable.
So when these two indistinquishable objects exchange velocities,
effectively NOTHING has happened.
There are still an immovable object at rest, and an unstoppable object with
velocity v1.
So, in this embodiment, the answer to “What happens . . . ?” is
“NOTHING!

An unstoppable object is impossible by definition in a universe with an
unmovable object and vice versa.
That is, the definitions of the two objects are mutually exclusive.
