Christian Sommerfeld is still having a problem:
Hi guys,

@Eugen: Thanks! Your summary explain exactly whati mean.  Sorry for the
bad formulated question!

Ok this makes sense. If you use the kinetic energy conservation and
momentum conservation  than you get the same velocity and the same
position. Thank you very much Jan!

First i though if you add the forces to the newton law there will be a
much higher velocity after the contact when using the law of cundall &
strack. So now i understand what the laws are doing. Every contact law
affects the time of actual contact what affects the position and the
velocity of the motion. And for a short time of actual contact the
impact of different laws isn't that high.  This explains the behaviour
for t>0.45 where the impact of the contact law is much higher. Hopefully
i understand it in the correct way?

Cheers,

Christian
