A 48.2 kg, 3.1 m uniform ladder leans against a frictionless wall. A 97.8 kg person is standing on the ladder down 0.96 m from the top of the ladder. The ladder makes an angle of 57 degrees with the horizontal. What is the minimum coefficient of static friction between the ladder and the ground so that the ladder does not slip?
A ladder of length 12.0 m with a mass of 40.0 kg leans against a smooth wall. The ladder makes a 35.0o angle with the horizontal. Draw an adequate free body diagram of the ladder and determine the minimum coefficient of static friction between the ladder and the ground necessary to prevent the ladder from slipping.

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...
An 18 kg person climbs up a uniform ladder with negligible mass. The upper end of the ladder rests on a frictionless wall. The bottom of the ladder rests on a floor with a rough surface where the coefficient of static friction is 0.25. The angle between the horizontal and the ladder is θ . The person wants the ladder a distance of 2.6 m along the ladder from the ladder's foot. to clim b up 4 m 2.6 m...
