No. Just apply conservation of momentum to the turnaround and it'll show that the pipe reverses:
conservation of momentum is the philosophic or
theoretical side of physics , and if it cannot
be proved corect by the math side of physics then
it is a flawed law.
this is a simple example that is easily
calculated , you used question marks instead of
filling in the amounts using math.
I repeat a 4000N force can accelerate a 1000 kg mass
to 4 m/s/s in 1 second , that mass will move a distance of
2 meters.
also , there is no additional force applied to the pipe
in the direction that would reverse the pipes direction.
you do agree that the 100kg mass traveling at 40 m/s
passing through the 1st turn will apply a 4000N force
to the 1st turn , correct?
and that this 4000N force will apply to the pipe, correct?
so if you agree on the above then the pipe will slow
from 4 m/s velocity to 0 m/s velocity in 1 second , correct?
lets just use math wherever possible.
because the math side of physics is the side that is used to check the theoretical side.
the theoretical side is not used to check the math side.
