A uniform chain of length $2.0\ \text{m}$ and mass $2.0\ \text{kg}$ lies on a rough horizontal table, with $0.5\ \text{m}$ of it hanging over a smooth, rounded edge, as shown in the figure. The coefficient of friction between the chain and the table is $0.2$. The chain is released and slides off. Take $g = 10\ \text{m/s}^2$. What is its speed at the moment the last link leaves the table?

Fig. 1: A uniform chain lies straight on a horizontal table and hangs straight down over the smooth rounded right edge of the table. 1.5 m of the chain is on the table, where the coefficient of friction is 0.2, and 0.5 m hangs down.
