Hiya, I'm not entirely sure where I should put this question, but as it isn't homework I thought this might be the best place for it. Anyways, I've been banging my head on this question for almost an hour now, and I've gotten absolutely nowhere. The question is that there's a chain hanging off the edge of a table with dynamic coefficient of friction of 0.1, where 1/5 is hanging off the edge and 4/5 is still on the table, and I need to find the velocity of the chain once it has completely left the table. What on earth do I do to solve this? I keep getting 3.92 ms^-1, but the answer should be 2.63ms^-1... Cheers, Just some guy.
