A chain of mass `m=0.80kg` and length `l=1.5m` rests on a rough-surfaced table so that one of its ends hangs over the edge. The chain starts sliding off the table all by itself provided the overhanging part equals `eta=1//3` of the chain length. What will be the total work performed by the friction forces acting on the chain by the moment it slides completely off the table?
