A 45.4 kg, 3.8 m uniform ladder leans against a frictionless wall. A 99.1 kg person is standing on the ladder down 1.04 m from the top of the ladder. The ladder makes an angle of 50 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?

1A) A 47.8 kg, 3.6 m uniform ladder leans against a frictionless
wall. A 87.7 kg person is standing on the ladder down 0.98 m from
the top of the ladder. The ladder makes an angle of 70 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?

A 5 m uniform ladder leans against a frictionless wall. The
coefficient of friction between the ladder and the floor is 0.35.
The base of the ladder is 4 m from the wall. If the ladder weighs
50 N, and a person is 3 m up the ladder (2 m from the top), what is
the most this person could weigh without causing the ladder to
slide? Show all work.

A uniform ladder of length L and mass m leans against a
frictionless vertical wall, making an angle of 57° with the
horizontal. The coefficient of static friction between the ladder
and the ground is 0.42. If your mass is four times that of the
ladder, how high can you climb before the ladder begins to
slip?

A uniform ladder of length L and mass m leans
against a frictionless vertical wall, making an angle of 55° with
the horizontal. The coefficient of static friction between the
ladder and the ground is 0.40. If your mass is four times that of
the ladder, how high can you climb before the ladder begins to
slip?

A uniform 6.0-m-long ladder of mass 15.0 kg leans against a
smooth wall (so the force exerted by the wall, F→W, is
perpendicular to the wall). The ladder makes an angle of 25.0 ∘
with the vertical wall, and the ground is rough.
Determine the coefficient of static friction at the base of the
ladder if the ladder is not to slip when a 77.0-kg person stands
three-fourths of the way up the ladder.

A uniform 6.0 kg ladder is leaning against a frictionless
vertical wall, with which it makes a 15 ?angle. The coefficient of
friction between ladder and ground is 0.26.
Can a 58 kg person climb to the top of the ladder without it
slipping?
If so, how massive a person would make the ladder slip?
