Question

A damp washcloth is hung over the edge of a table to dry. Thus,part (mass = mon) of the washcloth rests on the table and part(mass = moff) does not. The coefficient of static friction betweenthe table and the washcloth is 0.542. Determine the maximumfraction [moff/mtotal] that can hang over the edge without causingthe whole washcloth to slide off the table.

I'm not sure how to go about this problem. I think I'm supposed touse f = uF (where f=frictional force, u=coefficient of staticfriction, and F=normal force), but I don't know how to get thevalues for the mass.

And after I solve for f, am I done or are there more steps?

Thank you!
