Marble Run (with seesaw)

Problem description

File MarbleRunWithSeesaw.cpp shows one particle cascading down a Marble run track. The entire code of this problem can be viewed here: MarbleRunWithSeesawCode.
"Predicting single particle dynamics by modelling a Marble run" is the title of the Bachelor project by Sven van den Heuvel.
The program demonstrates the influence of the different properties of a particle. In Can you use physics to win a marble race? Prof. dr. Anthony Thornton demonstrates this on a real track with glass, wood, steel and other marbles. The used properties are: size(radius), mass, COR (correlation coefficient), sliding and rolling friction coefficient. The marble run itself is a STL-file containing a 3D CAD drawing and 2 separate seesaws.

full Trace of a bouncy ball, stuck in a seesaw.

The colour the the trace depends on the speed, red is high and blue is low speed.

It can even bounce Off track.
