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.
