Exactly. It's not a question that has a right answer. The professor probably doesn't even care about the final answer that you provide. What matters is the time you spent thinking about it and the thought process you used to get there.

For example, if you thought about Newton's Second Law, you could notice that it isn't always represented by F = m * a. Sometimes it's written F = dp / dt, i.e. the instantaneous change in momentum over time. The immovable object cannot be moved, so that means its momentum can never change. This means that it is impossible for any force to act on it. The unstoppable force similarly can't have its momentum change, and no outside forces can act on IT.

Now the real fun begins when you stop looking at things from the reference frame of the immovable object, and start looking at it from the reference frame of the unstoppable force. From the reference frame of the unstoppable force, it isn't actually moving at all, and it's the immovable object that's rapidly approaching IT.

The wall moves and the object stops.

Question is silly, unstoppable emplies it is infinitely high and cannot be turned into heat or sound energy?

I dont get it, when you get the answer pm me im interested.

Take Engineering Statics...

Why you add a - in that formula ?



Yeah

dats how babies made

There are a couple assumptions here that I think are fallacies.

An unstoppable force does not equal an infinite amount of force nor does an immovable object have to have an infinite amount of mass. Those are possible solutions but not the only ones.


If both objects are unable to be affected by outside forces then they can absolutely have finite force and mass values (although that is not necessary either) and still meet all requirements of being unstoppable and immovable respectively.

In this case both objects would pass through each other without even noticing that an intersection had occurred.

unstoppable force goes through the wall and out the other side provided it's absolutely unstoppable. the immovable wall doesn't move because the unstoppable force goes through empty space within the wall's atoms. at least that's how i interpret it.

Maybe when the force impacts the wall (at an angle?) it simply rebounds and continues on? The wall doesn't move, and the force isn't stopped.
