A uniform chain of length l and mass m overhangs a smooth table with its two third part lying on the table. Find the kinetic energy of the chain as it completely slips off the table.
A uniform chain of mass 6 kg and length 10 m is placed on a frictionless horizontal table. Due to a small jerk, chain starts to slide down from edge of table. Find the speed of chain when chain is slips off completely. [Height of table is greater than 10m]
