A uniform ladder 5.30 m long rests against a frictionless, vertical wall with its lower end 3.10 m from the wall. The ladder weighs 157 N . The coefficient of static friction between the foot of the ladder and the ground is 0.430. A painter weighing 739 N climbs slowly up the ladder.
How far along the ladder can the painter climb before the ladder starts to slip?

A uniform ladder 5.30 m long rests against a
frictionless, vertical wall with its lower end 3.10 m
from the wall. The ladder weighs 161 N . The coefficient
of static friction between the foot of the ladder and the ground is
0.390. A painter weighing 741 N climbs slowly up the
ladder.
a)What is the actual size of the frictional force when the
painter has climbed 1.0197 m along the ladder?
b)How far along the ladder can the painter climb before the
ladder starts...

length of the ladder (x / L) will the worker have reached
when the ladder begins to...

A uniform 5-m long ladder weighing 80 N leans against a
frictionless vertical wall. The foot of the ladder is 1 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?

A uniform ladder rests against a frictionless wall at an angle
of θ = 48.0° with respect to the ground. If the weight of the
ladder is WL = 250 N, the length is L = 9.0 m, and the coefficient
of static friction between the ladder and the ground is μs = 0.60,

A ladder 10 ft long rests against a vertical wall. If the bottom
of the ladder slides away from the wall at a rate of 1.4 ft/s, how
fast is the angle between the ladder and the ground changing when
the bottom of the ladder is 8 ft from the wall? (That is, find the
angle's rate of change when the bottom of the ladder is 8 ft from
the wall.)

A uniform ladder stands on a rough floor and rests against a
frictionless wall as shown in the figure. 2 58 1 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 N2 on the ladder. The ladder has a length of L
= 4.5 m, a weight of WL = 63.5 N, and rests against the wall...
