		+	I don't think I would ever see v' as "v at time zero", that's v<sub>0</sub>, or possibly v(0). v' is acceleration (assuming v is velocity).

	Ok, but the 2nd sentence in the explanation has a grammar mistake. The sentence reads, "Randall then makes a footnote about r, using."

		+	: I support this. r' can be the derivative of r = angular speed, r" the double derivative of r = angular acceleration. The joke is that r' and r" are horrible notations, because they are already have two meanings, giving them yet another meaning beyond derivative and "r measured in different frame of reference" would add to the existing confusion.
