Question

An 88 kg person stands on a uniform 5.6 kg ladder that is 4.0 m long, as shown in the figure(Figure 1). The floor is rough; hence, it exerts both a normal force, f1, and a frictional force, f2, on the ladder. The wall, on the other hand, is frictionless; it exerts only a normal force, f3.

Using the dimensions given in the figure, find the magnitudes of f1, f2, and f3.

Answer #1

In two significant figures answers are a) 920 N

b) 170 N and C) 170 N

Do let me know in case of any mistake .. I will rectify it asap...

Thank you...

A uniform 4m long ladder (ML = 50kg) is leaning against
the wall at 65° above horizontal. There is no friction between the
wall and the ladder but there is friction between the ladder and
the floor. Determine the normal forces on each end of the ladder
and the frictional force on the bottom of the ladder.

A uniform ladder has a mass of 16.0 kg and a length of 8.50 m.It
stands on the ground and leans against a vertical wall, making an
angle of 62 degrees with the ground. The friction between the wall
and the ladder is not significant.What is the smallest force of
friction between the ladder and the ground that will prevent the
ladder from slipping?

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?

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?

A 10.0 -kg monkey climbs a uniform ladder with weight w =
1.20x10^2 N and length L=3.00m (hypotenuse) as shown in the figure.
The ladder rests against the wall at an angle of theta = 60.0°. The
upper and lower ends of the ladder rest on frictionless surfaces,
with the lower end fastened to the wall by a horizontal rope that
is frayed and that can support a maximum tension of only 80.0 N.

A 25 kg uniform ladder is leaning at a 60o angle
against a frictionless wall. It is a slick day—the coefficient of
static friction between the floor and the ladder’s base is only
0.4. a. How far up the ladder (in terms of the fraction of the
ladder’s length) can a 75 kg person climb before the ladder begins
to slip? b. What is the minimum angle the ladder needs to allow the
person to climb to the very top...

A 2.0-m-long, 11-kg ladder is resting against a house wall,
making a 35 ∘ angle with the vertical wall. The coefficient of
static friction between the top of the ladder and the wall the
coefficient is 0.00:
A. Determine the minimum coefficient of static friction between
the ladder feet and the ground needed for the ladder to stay in
rest.
B. Determine the magnitude of the normal force of the wall on
the ladder.
C. Determine the magnitude of the...

On a Romanian infomercial the 75.0 kg presenter attempts to
climb a 2.25 m long ladder with a mass of 5.00 kg at an angle of
70.0°. The ladder is held up by two other presenters that act as a
frictionless wall. The man on the ladder reaches a height of 1.80 m
when the ladder slips.
a) Solve for the normal forces on the ladder.
b) Solve for the coefficient of friction between the ladder and
the floor.
