A cork, say from a wine bottle, is held by a robotic clamp at the bottom of a bucket of water and released the moment the bucket is dropped off the side of a tall building. What will happen to the cork during the fall? Will it float to the top of the bucket normally, slower than normal, faster than normal, or not at all?

Assume that there is no air resistance to slow the bucket down.

the relativistic cork, that's the perspective that you wish to discuss: the acceleration of gravity is canceled by any free falling(satelites actually drop at a tangent trajectory to earth, so the movement is infinite) the archemedic force wich is responsible for the cork's floating is in direct relation with the gravitational acceleration, so the force will not exist in this case.

the cork will hold it's relative position in the bucket. If one dosen't consider the bernoulli effect on the top of the bucket!!!!!!
