Question

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 0.48. If your mass is four times that of the ladder, how high can you climb before the ladder begins to slip?

Answer #1

A ladder having a uniform density and a mass m rests
against a frictionless vertical wall, making angle 49.0° with the
horizontal. The lower end rests on a flat surface where the
coefficient of static friction is µs = 0.410. A window
cleaner with mass M = 2m attempts to climb the
ladder. Given a ladder length of L, what fraction of the
length of the ladder (x / L) will the worker have reached
when the ladder begins to...

A ladder having a uniform density and a mass m rests
against a frictionless vertical wall, making angle 50.0° with the
horizontal. The lower end rests on a flat surface where the
coefficient of static friction is µs = 0.420. A window
cleaner with mass M = 2m attempts to climb the
ladder. Given a ladder length of L, what fraction of the
length of the ladder (x / L) will the worker have reached
when the ladder begins to...

A uniform ladder of length l and mass m rests against a smooth,
vertical wall. The coefficient of static friction between ladder
and ground is 0.35. Find the minimum angle at which the ladder does
not slip. (Consider the torques about an axis perpendicular to the
page through O)

A uniform ladder rests against a frictionless wall at an angle
of
θ = 50.0°
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 = 0.65,
determine the distance a man with a weight of
WM = 800 N
can climb along the ladder before the ladder begins to slip.

A uniform ladder rests against a frictionless wall at an angle
of θ = 54.0° with respect to the ground. If the weight of the
ladder is WL = 240 N, the length is L = 7.0 m, and the coefficient
of static friction between the ladder and the ground is μs = 0.55,
determine the distance a man with a weight of WM = 875 N can climb
along the ladder before the ladder begins to slip
. ______m

A 52.5 kg, 3 m uniform ladder leans against a frictionless wall.
A 93.9 kg person is standing on the ladder down 1.14 m from the top
of the ladder. The ladder makes an angle of 60 degrees with the
horizontal. What is the minimum coefficient of static friction
between the ladder and the ground so that the ladder does not
slip?

Part A
A uniform 5-m long ladder weighing 80 N leans against a
frictionless vertical wall. The foot of the ladder is 4 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?

Romeo takes a uniform 11.5-m ladder and leans it against the
smooth wall of the Capulet residence. The ladder's mass is 24.0kg,
and the bottom rests on the ground 2.80m from the wall. When Romeo,
whose mass is 70 kg, gets 87.0 percent of the way to the top, the
ladder begins to slip. What is the coefficient of static friction
between the ground and the ladder?

An 8.00 m, 201 N uniform ladder rests against a smooth wall. The
coefficient of static friction between the ladder and the ground is
0.600, and the ladder makes a 50.0o angle with the
ground. How far up the ladder can an 801N person climb before the
ladder begins to slip?

A 6 m long, uniform ladder leans against a frictionless wall and
makes an angle of 58 ◦ with the floor. The ladder has a mass 26.4
kg. A 68.64 kg man climbs 82% of the way to the top of the ladder
when it slips and falls to the floor. What is the coefficient of
static friction between the ladder and the floor?
