Problem
A cube has vertices 
, and 
. At 
, a particle is at 
. After one second, the particle travels to 
. The particle bounces until it hits an edge or a corner at which point it stops. If the particle travels in straight lines with uniform speed, find the time (in seconds) when the particle stops motion.
