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 5.0 m long rests against a frictionless, vertical wall with its lower end 3.0 m from the wall. The ladder weighs 160 N. The coefficient of static friction between the foot of the ladder and the ground is 0.40. A man weighing 740 N climbs slowly up the ladder. What is the maximum frictional force that the ground can exert on the ladder at its lower end? What is the actual frictional force when the man has...

A uniform ladder 12 meters long rests against a vertical frictionless wall, as shown in the figure. The ladder weighs 400 N and makes an angle θ = 51° with the floor. A man weighing 874 N climbs slowly up the ladder. When he is 78 m from the bottom of the ladder, it just starts to slip. What is the coefficient of static friction between the floor and the ladder? 7.8 m
A uniform ladder of length L and mass m leans against a frictionless vertical wall, making an angle of 49° with the horizontal. The coefficient of static friction between the ladder and the ground is 0.45. If your mass is four times that of the ladder, how high can you climb before the ladder begins to slip?
A uniform 4m long ladder (ML = 50kg) is leaning against the wall at 65° above horizontal. There is no friction between the wall and the ladder but there is friction between the ladder and the floor. Determine the normal forces on each end of the ladder and the frictional force on the bottom of the ladder.
A uniform 5-m long ladder weighing 80 N leans against a frictionless vertical wall. The foot of the ladder is 2 m from the wall. What is the minimum coefficient of static friction between the ladder and the floor necessary for the ladder not to slip?
