"There are no tricks, gotchas or other devious ruses. Don’t rat-hole with issues related to terminal velocity, potential energy or wind resistance. This is a math puzzle plain and simple." Not out of the rules either (according to what you just posted). At some point you need to crush an egg. If the rules are implying that you can only do X and we are only looking for solution Y then why are we even talking about this? We may as well have a discussion about trains leaving from Chicago and New York and debate what city they will intersect from on a given day.
