OK, that's one mass turning around. Now do it for the other 49 masses. See if the red cart changes direction.



at 60 seconds the pipe has a mass of 5000 kg
and a velocity of 20.59908 m/s so its momentum is

+102995.4Ns

results are
red cart v = +18.22264549019608 m/s
blue cart v = +78.82172549019607 m/s

now lets do 80 seconds

at 80 seconds the pipe has a mass of 3000 kg
and a velocity of 48.25031 m/s so its momentum is

+144750.934Ns

results are
red cart v = +42.556741612903224 m/s
blue cart v = +130.80705161290322 m/s

now lets do 100 seconds

at 100 seconds the pipe has a mass of 1000 kg
and a velocity of 121.7047 m/s so its momentum is

+121704.74Ns

results are
red cart v = +92.30384545454545 m/s
blue cart v = +254.00854545454547 m/s

note :
I did not subtract or add the resultant velocities of the pipe or the mass and include them for each calculation above
therefore the differences will be extremely different.

ie...the results above wont even touch the true results.
because by decelerating the mass the 4000N I did use will be much greater so the pipe will be accelerating much faster than the above.
which means that the pipe velocity will increase greatly each second.


but I will do that today.

but from the looks of it your going to need a lot of stuff on the spacecraft that uses electricity , because the blue cart has really gained speed through the turn.

perhaps some type of deflector shield and a molecular transporter would consume the extra electricity generated.

and of cource we shouldnt forget the phaser banks and photon torpedoes.

LOL

btw

the wiki web site says that when a more massive body collides with a less massive body the more massive body does not change its velocity.

and the less massive body then has twice the speed of the more massive body less its original speed.

Quote:
Thus the more massive body does not change its velocity, and the less massive body travels at twice the velocity of the more massive body less its own original velocity. Assuming both masses were heading towards each other on impact, the less massive body is now therefore moving in the opposite direction at twice the speed of the more massive body plus its own original speed.


but surely you want something for your -4000Ns momentum influence !! to use to slow or stop the pipe.

but since were using a 100% elastic collision
you cant have anything to use !!!

LOL


resistance is futile
you will be assimilated

I guess all I have to do is make the 100 kg mass speed twice the speed of the pipe and add its original speed to it as it enters the decelerator.

before each 1 second calculation after the 51st second of course.

and add the extra momentum that the pipe will receive due to the extra speed that the 100 kg mass has after passing through the turn.

thats what I'll do today.


3/4 inch of dust build up on the moon in 4.527 billion years,LOL and QM is fantasy science.
