Terminal Velocity of a Ping Pong Ball

In a recent lab using Acumen the question of what is the terminal velocity of a ping pong ball came up.  Using a back of the envelope calculation, we estimated it and used that to compute a drag coefficient.  It turned out that we had come in within 20% of a number published in a research paper!

Thanks to Slawomir Nowaczyk for pointing us to this paper.

A draft paper is now available describing the main features of the proposed core language for Acumen.  The language described is supported by the current implementation. (Please see updated version above).
