okay, here's the real answer
while logically b makes sense since the velocity and inertia of the platform should be transferred to the cube, canonically the game says that inertia is preserved, so B can't happen
HOWEVER
a also cannot happen because the inertia of the cube is 0, so it cannot move through the portal at all; this is reflected in the game engine when the experiment is enacted, the portal hits the cube and stops
