<Taris> also, this I must share.  It comes right out of my
physics text book
* Ssithl prepares for brainmelt.
<Taris> A hockey puck, mass 0.115kg, moving at 35 m/s, strikes
an octopus thrown onto the ice by a fan.  The octopus has a
mass of 0.265 kg.  The puck and octopus slide off together. 
Find the velocity.
<Taris> yeah, this is one that the authors put in for those
students that stay up late trying to do these
