A ladder rests inclined against a wall (in much the same way as in the example we did in class). Would you feel safer climbing up the ladder if you were told that the floor was frictionless, but the wall was rough, or that the wall was frictionless, but the floor was rough? Justify your answer.

A uniform ladder stands on a rough floor and rests against a frictionless wall as shown in the figure. Since the floor is rough, it exerts both a normal force n, and a frictional force r, on the ladder. However, since the wall is frictionless, it exerts only a normal force N, on the ladder. The ladder has a length of L = 4.3 m, a weight of w. = 67.5 N, and rests against the wall a distance d...

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 3 m long ladder weighing 200 N rests against a smooth vertical wall with its base on a horizontal rough floor, a distance of 1 m away from the wall. If the center of mass of the ladder is 1.20 m from the base, what frictional force must the floor exert on the base of the ladder in order for the ladder to be in static equilibrium?
