in reference to the link you posted and the first flash
collisions in 1-d

if you replace the mass A with 1000 kg
and
mass B with 100 kg

mass A being the 1000 kg pipe
mass B being the 100 kg mass

and velocity of A to 4 m/s

you will see that mass B ( which would be the mass ) in our discussion almost doubles the velocity of mass A.

it would be nice if you could find a flash as in the above that would actually have a mass passing through a turn.

that you could set the mass and velocity of each.

the flash is not correct because if you set both A and B to 1000 kg and set the velocity of A to 1 m/s
you end up with more kinetic energy than you started with.

A with a velocity of 0.9 m/s
B with a velocity of 1.0 m/s

the kinetic energy you started with was
A and a velocity of 1.0 m/s

so the flash must be wrong.
