A uniform chain of length 8.00m initially lies stretched out on a horizontal table. a) If the coefficient of static friction between the chain and the table is 0.600, show that the chain will begin to slide off the table if at least 3.00m of it hangs over the edge of the table. b) Determine the speed of the chain as all of it leaves the table, given that the coefficient of the kinetic friction between the chain and the table is 0.400. I do not have a clue on how to draw up an FBD and start working on the problem. I kind of think it has to do with partial derivatives since the length of the chain, its mass hanging off the edge and its speed and acceleration varies with time. Can someone please, help me out to get started by giving a direction or a generic setup which I can start to work with. Thank you in advance!
