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.

figure can be found at

Thanks

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

I see the image, before you get help you must show your thoughts about the problem. Say something about it.
