Matt & Hugh play with a Brick and derive Centripetal Acceleration

Matt and Hugh play with a tennis ball and a brick. Then they do some working out to derive the formula for the centripetal force (a = v^2/r) by differentiating some vectors.

Here are the sheet of working out: http://imgur.com/a/lphOr

This is a new video format idea, so all feedback appreciated!
(Sorry the audio goes a bit out-of-phase; fixing it for this video was beyond my current skill × time, but I'll fix it next time.)
