A uniform chain of length 8.00m initially lies stretched out on a horizontal table.(adsbygoogle = window.adsbygoogle || []).push({});

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 have solved part a no problem. Part b I am having a lot of problems with. I am trying to fill in the equation U(init)+K(init)-W(fric)=U(final)+K(final)

I understand that the right side is U(final) is 0 and K(final) is 1/2mv^2. How about the left side?

Thank you in advance
