I found your error...
you use the mass*acceleration to get the 8000N
then you use the same to get another 8000N to act against the pipe.

the mass and the pipe both experience the same 8000N
you cannot seperate this action and then get two seperate forces from it.

Quote:

The mass spends 1s turning around.
It enters with a _velocity_ of -40m/s
It leaves with a velocity of +40m/s
It's velocity changes by (+40m/s) - (-40m/s) = 80m/s
It does that change in 1s.
Acceleration = (change in velocity) / (time taken)
Acceleration = 80m/s / 1s = 80m/s^2
The _mass_ must experience a +ve force to turn around. That force is:
F=ma
F=100kg * 80m/s^2
F=8000N
Furthermore, the pipe must experience the same force that the mass does, but in the opposite direction. That force is
F_pipe = -8000N


the 8000N is divided between the mass and the pipe.
4000N goes to the pipe as I have always said.

you dont get your extra free force to move the
pipe in the opposite direction.

in order for you to apply a 8000N force to the mass and a 8000N force to the pipe , you would need 16,000N

so the pipe stops , and your bulls&^$t stops also.
im pretty much tired of your scammy ways kallog

end of our discussion.
