A uniform 6.0-m-long ladder of mass 15.0 kg leans against a smooth wall (so the force exerted by the wall, F→W, is perpendicular to the wall). The ladder makes an angle of 25.0 ∘ with the vertical wall, and the ground is rough.
Determine the coefficient of static friction at the base of the ladder if the ladder is not to slip when a 77.0-kg person stands three-fourths of the way up the ladder.

A uniform plank of mass M and length L leans
against a vertical wall. The initial angle it makes with the
horizontal ground is 60º. It is let go from rest and slides down
frictionlessly. The moment it leaves contact with the wall, what
angle does it make with the ground? There is no friction
anywhere.
