I don’t know how well the maths of QM simplify, but if you were to set up the above problem in QM would you end up being able to essentially simplify the math down to the well known classical equations that describe the balls motion?

The only point of these questions is to help me to realize the connections between these two seemingly very different ways of looking at things (QM and classical). I feel there must be some connection because at one scale they should both give the same exact results.
