5. A uniform 8.0 m long ladder of mass 10.0 kg leans against a wall. The wall is smooth and the floor is rough. The coefficient of static friction between the ladder and the floor is 0.35 (i) Draw a sketch and free body diagram. (ii) Find the reaction force from the wall. (iii) Find the normal force at the ground. (iv) Find the minimum angle at which the ladder does not slip.
A 100N uniform ladder, 8.0m long, rests against a smooth vertical wall. The coefficient of static friction between the ladder and the floor is 0.40. What minimum angle can the ladder make with the floor before it slips? OPTIONS 22˚ 51˚ 18˚ 42˚

A uniform ladder of length L and mass 5 kg rests against a smooth, frictionless, vertical wall. The coefficient of static friction between the ladder and ground is 0.4. a.) Draw a force diagram indicating all the forces acting on the ladder and where they are applied. b.) Find the minimum angle,between the ladder and the ground at which the ladder will not slip.
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?
D. DOLH A and B 18. A uniform, 5.0-m ladder rests against a slippery vertical wall. The inclination angle between the ladder and the rough horizontal floor is 53°. If the ladder weighs 400.0 N, show that the coefficient of static friction that just prevents the ladder from slipping is 0.38.
The ladder has a uniform weight of 80 lblb and rests against the wall at B. If the coefficient of static friction at A and B is μμmu = 0.41, determine the smallest angle θ at which the ladder will not slip. Note: friction is on both the wall and the ground.
A 5.0-m long, 15-kg uniform ladder rests against a smooth vertical wall with the bottom of the ladder 3.0 m from the wall. The coefficient of static friction between the floor and the ladder is 0.38. What distance, measured along the ladder from the bottom, can a 70-kg person climb before the ladder starts to slip? Question 2 (1 point) A 5.0-m long, 15-kg uniform ladder rests against a smooth vertical wall with the bottom of the ladder 3.0 m...
