Ok, we are going now to extract some data
first we will start with
S(t) where our input was the time (clock) and angular velocity
The next will be
Xs and it should look like below
We can see also the
friction force
And
air cushion force
And finally is the most important force,
impact force
We can see clearly it is some of impulses acting sequentially with impact time so small, anyway by zooming in the draw you can see the width of the impact time
