To do the reflection we only need the mirror at Z=0, it doesn't matter which way it is facing, so the translations can be replaced with a 180 degree rotation around a point halfway between the mirror and the origin, ie. In other words, the rolling motion of a rigid body can be described as a translation of the center of mass (with kinetic energy Kcm) plus a rotation about the center of mass (with kinetic energy Krot).
