because it started with 8000 N.s

anything under or over 8000 N.s will violate the laws of conservation of momentum.


Can you provide a reference to those laws? It's different from everything I've ever seen.


Here's common-sense proof it's wrong:

Two identical 1kg objects, each travelling at 4000m/s collide head on and stick together. After they stick together you say the 2kg blob will be moving at 4000m/s.

Please confirm that's what you predict to make sure I'm not misunderstanding you.
