Assuming portals do not alter any Newtonian and classical mechanics, the cube is not accelerated at all by either portal. Simply going through the portal does not change your velocity, acceleration, or jerk; rather, it only changes your position via teleportation. Thus, the infinitesimal slices of the cube (since it has to pass through the portals) are placed instantaneously in the location of the orange portal's center. The cube then accelerates at that point due to the force of gravity acting on the block's center of mass.

Please ignore that I assigned the portals a letter to be called by when I didn't use it, I thought I was going to write more. Here is the acceleration of the block instead of speed. If you truly want the speed, I can integrate my answer for you, just ask.
