SUMMARY
The discussion centers on the conservation of momentum during collisions, specifically addressing the interaction between two objects with defined momenta. Object A has a momentum of 10 kg m/s horizontally, while Object B has a momentum of 20 kg m/s up-diagonally. According to the principle of conservation of momentum, the total momentum of the system must remain constant post-collision, meaning the resultant momentum can be redistributed but must equal the initial total momentum of 30 kg m/s. Therefore, it is not permissible for the post-collision momentum to be 15 kg m/s horizontally and 15 kg m/s up-diagonally, as this would violate the conservation principle.
