A uniform ladder of length L rests against a smooth frictionless
wall. The floor is rough and the coefficient of static friction between
the floor and ladder is m. When the ladder is positioned at angle q,
as shown in the accompanying diagram, it is just about to slip. What is
q?

A. q =m/L

B. tanq = 2m C. tanq =12m

D. sin q =1m

E. cosq = m
