The coefficient of statis friction between a rope and the table on which it rests is 0.3. Find the fraction of the rope that can hang over the edge of the table before it begins to slip. This is an extra credit problem so we haven't learned this yet. I don't know where to start but i'm guessing that to find that fraction of the rope, you need the mass,the weight and the gravitational force and stuff?? cluless >.< please help.
