Hello again ABV.
I think you need a way to control for air resistance, or at least confirm that it's low enough not to affect the results.
I still don't understand why you want to do it when you're only confirming very old and well-tested theory. You expect the same result as theory predicts.
It would be nice to formulate rotational and translational momentum conservation as a single concept. But how will this experiment help you do that? It will confirm the classical result and leave you having to develop the general momentum theory in exactly the same way you'd have had to do it anyway.
Well, I don't want to jump up to conclusion without real experiment results. If result will show identical value of translational velocities then it will prove modern physics motion concept. If not then modern physics does not cover all natural phenomenons yet and motion concept should be corrected. At first, I want to get results from real experiment.
