as far as I can tell , with the use of physics math
the 100 kg mass that has a original speed of 40 m/s will inherit 13.49721 m/s x 2 = 26.99442

for a grand total of 66.99442 m/s speed

so its velocity would be +66.99442 m/s

the following formula is used to find force using
distance , time , momentum
http://en.wikipedia.org/wiki/Force



distance = 1000 meters
time = 50 seconds
momentum = 100 kg x +66.99442 m/s


momentum = 100 kg x 66.99442 m/s = 6699.442Ns

distance x momentum = 1000 meters x 6699.442Ns = 6699442

distance x time = 1000 meters x 50 seconds = 50,000


F = 6699442 / 50000 = 133.98884N

so during the time period between 51 seconds to 52 seconds the pipe will have a force of
+134N and a force of +4000N causing it to accelerate.

after this second has passed the pipes momentum will become higher than the previous second.

which should cause the next 100 kg mass to have a even higher speed as it leaves the turn.

etc etc etc ,,, bla bla bla...

I'll finish it later , Im trying to put this in a program.
