Question: A chain of length is held stretched out on a frictionless horizontal table, with a length y0 hanging down through a hole in the table.

A chain of length ℓ is held stretched out on a frictionless horizontal table, with a length y0 hanging down through a hole in the table. The chain is released. As a function of time, find the length that hangs down through the hole (don’t bother with t after the chain loses contact with the table). Also, find the speed of the chain right when it loses contact with the table.
