Rope through hole

A rope of length 90 cm\SI{90}{\centi\meter} lies in a straight line on a frictionless table, except for a very small piece at one end which hangs down through a hole in the table.

This piece is released, and the rope slides down through the hole. What is the speed ((in m/s)\text{m/s}) of the rope (to 2 decimal places) at the instant it loses contact with the table?

Details: g=9.81 m/s2.g = \SI[per-mode=symbol]{9.81}{\meter\per\second\squared}.
