A chain of length L and total mass M is released from rest with its lower end just touching the top of a table, as in figure

(a). Find the force exerted by the table on the chain after the chain has fallen through a distance x, as in figure (b).

Assume each link comes to rest the instant it reaches the table.

The answer is 3xgM/L if you wonder. I want to know how that is achieved.
