It went through the portal at speed, so it should exit the portal at speed. That’s my take.

If we could test it, I think it would be helpful to put portals on either side of a very light, plastic disk in an attempt to see if it works like a hula hoop or not. If we drop the hoop over the cube, would the hoop:
Just land on top of the cube because the hoop has far less energy than a much more massive cube traveling at the same velocity?
Drop around the cube, such that the cube is just sitting on top of the exit portal?
Launch the cube into the air with an initial velocity equal to that of the hoop when the cube entered the portal? If so, where does all the additional energy required to accelerate the cube come from if the hoop’s momentum is far less than the cube’s momentum at the same velocity?
