A uniform chain of length L lies on a smooth table with part of its length b initially hanging over the edge. Show that the time required for it to fall off the table when released from rest is given by
t = √(L/g) arccosh (L/b)
The Attempt at a Solution
Not sure how to begin, since the acceleration of the chain keeps increasing as b increases. b is in turn related to the acceleration of the chain.
