I like this question. Nobody knows the answer but me.

No such thing as unstoppable.. They either disintegrate, rebound, or one pushes the other, depending on characteristics of objects.

All colliding objects in a friction-free world must follow the rule that momentum is conserved. Any question posed in a physics forum *must* allow for this! If the momentums of two objects match exactly except that they are in opposite directions, and they meet head on, then the conservation of momentum, which *must* be obeyed, says that the net momentum after impact *must* be zero. This can mean that the two original objects each now have zero velocity (have stopped), or that they have fragmented and the net momentums of all the fragments travelling in all directions adds to zero, or that the original objects bounce off one another such that the net momentum is zero (as in travel at 180 degrees from their original direction). The last choice (bounce off and reverse directions) of course implies that the velocities of each at some instant after impact is zero, so they mometarily stop.
Perhaps you would like to flesh this problem out a bit more, and define what you mean by "unstoppable" in the context or actual physics, as it appears inconsistent with the Law of Conservation of Momentum.

Sir you don’t give us any clue about their velocity and mass
But no matter what, they can only fall in to one of Newton’s 3 laws of motion
Probably in to the law of inertia or the 2nd law
So if they both have the same acceleration and mass let is say 10Newton, the other object must have –10 Newton becuz they collide means they are both going in the opposite direction so one of them must be negative and we will finally get –10 + 10 which is 0 that means they will forever remain at where they collide or in the other case if one of them have more acceleration than the other they will decelerate along the direction of the object that has the maximum acceleration with lower speed than their original.

Ok, how many times must I answer this.
First, nothing is unstopable, just like nothing is immovable. End of that discussion, even stars move.
However, you can, in a thought question stipulate something that is impossible as long as it is consistant in the question.
So, you can stipulate one unstopable object, but not two.
More:
I answered this question a few weeks ago, and I stand by it. In a logic or thought problem, you can not ask such a question, it has no meaning, and therefore no answer.
it is the same classic logic question about an irresistable force and an unmovable object. You can not have both.

Two unstoppable objects of equal mass, size, and velocity traveling at on another would cancel each other out and come to an instantaneous halt as the equaled kinetic forces are transformed into heat....however, since both unstoppable objects stopped refer to par 2.
Two unstoppable objects of differing mass, size, and velocity would strike one another and the greater force would slow, over power and continue on course pushing the smaller "unstoppable force" in it's direction. However, since the smaller unstoppable force stopped refer back to par 1.

The situation is not possible.
In the core collapse of a super nova this would be the closest you could get to such a situation.
The fact that they are quantum entities allows nature to let these two objects pass through each other.
Consider two iron plates and two steel pinned dog brushes.
The irons will stop each other but the dog brushes will pass through each other.
Aw,comon give us the answer.

The two objects wound impact and the debri would fan out in 360 degree directions.

The outcome would be an unstopable colision ,among other things.
This is really a very interesting question; the complete answer would require the volume of abook and still it may not be understood.

They would transit into an alternate universe where they would continue being unstoppable!!

They would bounce off each other and continue in the opposite directions.
