A nonuniform ladder is leaned against a frictionless wall. The ladder has a mass of 30 kg, a length of 10.0 m, and makes a 60° angle with the ground. The coefficient of static friction between the ladder and the ground is 0.42. Assume g = 10.0 m/s^2 a. If a 75 kg firefighter is able to climb 90% of the way up the ladder before it begins to slip, where is the center of mass of the ladder located...

A uniform ladder of mass m and length
l leans at an angle
against a frictionless wall. A person of mass M climbs 90% of the
way to the top (at 0.9l). Find an expression for the minimum
coefficient of static friction needed to keep the ladder from
slipping.
