Paul, why are you still using numbers and units? Just stop it. You know that you cannot use algebra (you yourself said it's not right). You know you cannot use units (don't argue that again until you have a 3rd party or experimental results to support you). You know you can't distinguish between momentum, force and impulse.

So you want to know where your mistakes are? I already showed you. I don't need to go back and work it out again if you can't be bothered either.

Here's something else which makes your reason meaningless - An object that was accelerated by a 70,000N force can be stopped by a -4000N force. Yes it can, you can test it yourself with bathroom scales and toy cars, or something along those lines.
