Homework Help: Physics

In moving a 35.0 kg desk from one side of a classroom to the other, a professor finds that a horizontal force of 300 N is necessary to set the desk in motion, and a force of 185 N is necessary to keep it in motion at a constant speed.
(a) What is the coefficient of static friction between the desk and the floor?
(b) What is the coefficient of kinetic friction between the desk and the floor?

Could someone please help me? I'm totally lost...I know that
Fsmax = us(mg)...
