A flexible in -extendable chain of length L = 5 m and weight 10 kg is held on a smooth table with an initial overhang a = 2 m as shown in the following figure. Calculate the velocity v with which the chain will leave the table if released. (Consider acceleration due to gravity. g = 9.8 m/s2)

3.2 m/s
2
6.4 m/s
3
2.1 m/s
4
