Not what you're looking for?
A table of height 1 meter has a hole in the middle of its surface. A thin, gold chain necklace, of length 1 meter, is placed loosely coiled close to the hole. One end of the chain is pulled a little way through the hole and then released. Friction is negligible, and, as a result, the chain runs smoothly through the hole with increasing speed. At what times will the two ends of the chain reach the floor?
