The pink spheres cause an acceleration of 1 cm per second squared towards themselves. The aqua spheres cause an acceleration of 2 cm per second towards themselves. All spheres have the same mass. The spheres are attached to a massless, yet mysteriously solid perfectly circular green ring, equidistant from the closest spheres (pi/2 from one another). The 10 cm diameter green ring is rotating at a velocity of 1 cm per second. Everything except the pedestal experiences an acceleration of 10 cm per second squared downwards (in the direction from the bearing towards the pedestal). The pedestal is fixed in place (does not accelerate downwards). The ring is held up from the pedestal by a post with a frictionless bearing. At what rate does the velocity of the ring change over time if acceleration transmission is instantaneous? At what rate does the velocity of the ring change over time if acceleration transmission is relativistic?
