4000Ns, not 4000N. This is the impulse applied to the pipe, not the force. It's also the momentum added to it. The force is 80N because you defined the force to be 80N.

I think it would be best if you did your own calculations and if our calculations are different then we can discuss them.

No. That will lead to another confusing mess. You can just show each step of the machine, and what happens to the relevant variables (velocity/etc).

You can probably get your program to show the results after each change.

I already wrote a program for the complete 1-mass system. You didn't bother to even read the code or paste it into your own program, or run it, or anything. So I don't want to waste time doing that again.
