A uniform chain of length 8.00m initially lies stretched out on ahorizontal table.
(a) If the coefficient of static friction betweenthe chain and the table is .600, show that the chain will begin toslide off the table if at least 3.00 m of it hangs over the edge ofthe table.
(b) Determine the speed of the chain as all of it leavesthe table, given that the coefficient of kinetic friction betweenthe chain and the table is .4.
