    Status: Open => Answered

Bruno Chareyre proposed the following answer:
 >I expected the force on each sphere should be dissipated 1/2 from the
previous force because I set up the resttitution coefficient between
soil and soil equal to 0.5

Only energy can be dissipated, not forces. Restitution coefficient is also usually defined as a ratio of energy after/before collision, not as a ratio of forces.
Why do you think the forces per body should follow a logical rule during a complex event like this?
