Let say we have a non-deformable object and we release it into free fall and it hits the non-deformable floor. What would happen?
Here is the way I think.
Since the floor and the object are both non-deformable, there is no chance that the object will bounce. If we assume the Earth to be at rest before and after the collision (*), the object stops suddenly (like in 0,0000000000.. second) and that means the acceleration and the force are infinitely big.
This reasoning makes me think that there are no such things as perfect non-deformable bodies but let say we use the closest object and the floor to conduct the experiment. What would happen both in terms of momentum and energy conservation?
*In reality the Earth would be moving towards the object during free fall so that the center of mass of the system stays unchanged.
