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
N1
and a frictional force
f1
on the ladder. However, since the wall is frictionless, it
exerts only a normal force

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...

An 85kg person stands on a uniform ladder 4.0m long, that weighs 100N, as shown in the figure. The floor is rough; hence, it exerts both a normal force, f1. and a frictional force, , on the ladder. The wall, on the other hand, is frictionless; it exerts only a normal force, fs. The ladder makes angle of 60.0 with the floor. Find the forces exerted on the ladder when the person is three-fourths of the way up the ladder.

(2-3) A 3.0 m long ladder leans against a frictionless wall at an angle of 60° as shown. Assume the ladder is uniform with its center of mass at its geometrical center and that it is in equilibrium. 2. Which forces cancel/force cancels the weight of the ladder? a. The normal force exerted on the ladder by the floor. b. Both the normal force exerted on the ladder by the floor, and the frictional force exerted on the ladder by...

A 16.0 m uniform ladder weighing 480 N rests against a frictionless wall. The ladder makes a 58.0 degrees angle with the horizontal. Find the horizontal and vertical forces the ground exerts on the base of the ladder when an 800 N firefighter is 3.80 m from the bottom. Magnitude of the horizontal force Your response differs from the correct answer by more than 100%. Direction away from the wall towards the wall Magnitude of the vertical force If the...

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 16.0-m uniform ladder weighing 400 N rests against a frictionless wall. The ladder makes an angle of 60.0 degree angle with the horizontal. A 700-N firefighter climbs 5.00 m up the ladder, Draw a free-body diagram for the ladder. Find the force exerted by the wall on the ladder If the ladder is just on the verge of slipping when the firefighter is 10.00m up, what is the coefficient of static friction between ladder and ground?
