Hello,

I would like to ask you for a help with solving a differencial equations for oscillator damped by a constant friction force (no damping force proportional to the velocity!)

General solultion:

Where 

The amplituce A is decreasing by C at each turning point and center of the ascillatory motion moves: x = -C/2 or x = C/2

Moving:

where

How to create a graphic output of movement according to equation x(t) similar to graph mentioned below?

Thank a lot for your help. I have been working on this task for several weeks without success.

Tom
