A chain of mass m and length l rests on ...

A chain of mass m and length l rests on a roung surfced 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 `1//3`of the chain length. What will be the total work performed by the fricition forces acting on the chain by the moment is slides completely off the table ? Friction cofficient is `mu`

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?

A uniform chain of mass m_0 and length l rests on a rough incline with its part hanging vertically as shown in the fig. The chain starts sliding up the incline (and hanging part moving down) provided the hanging part equals eta times the chain length ( eta lt 1). What is the work performed by the friction force by the time chain slides completely off the incline. Neglect the dimension of pulley and assume it to be smooth.

A chain of mass m and length 1 lies on a rough table. The chain just starts to slip when the overhaning part equals n^(th) fraction of the chain length. If the chain is slightly distributed so that it completely slips off the table, what is the work performed by the friction forces.
