Question

- A ladder whose length L is 12 m and mass m are 45 kg rests against a wall. Its upper end is a distance h of 9.3 m above the ground. The center of mass of the ladder is one-third of the way up the ladder. A fire fighter whose mass M is 72 kg climbs the ladder until his center of mass is halfway up. Assume the wall but not the ground is frictionless. What forces are exerted on the ladder by the wall and by the ground? Provide both the magnitude and direction of the ground and wall forces. Please, if this is going to be written, write it so it is legible. Thank you!

A
10 m ramp with a mass of 5.0 kg rests against a wall. The end of
the ramp touches the wall at a height (h) of 1.5 m. The center of
gravity for the ramp is halfway up the ramp. A crate with a mass of
10.0 kg rests halfway up the ramp. What forces are exerted on the
ramp by the wall and by the ground, assuming that the wall is
frictionless but the ground is not? My...

In the figure, a ladder of length L = 10 m and mass m = 44 kg
leans against a slick (frictionless) wall. The ladder's upper end
is at height h = 7.9 m above the pavement on which the lower end
rests (the pavement is not frictionless). The ladder's center of
mass is L/3 from the lower end. A firefighter of mass M = 68 kg
climbs the ladder. Let the coefficient of static friction μs
between the ladder...

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 ladder of length L = 2.7 m and mass m = 21 kg rests on a floor
with coefficient of static friction μs = 0.55. Assume the wall is
frictionless.
1)What is the normal force the floor exerts on the ladder? 205.8
N
2)What is the minimum angle the ladder must make with the floor
to not slip?
3)A person with mass M = 68 kg now stands at the very top of the
ladder. What is the normal...

with coefficient of static friction μs = 0.56. Assume
the wall is frictionless.
1)
What is the normal force the floor exerts on the ladder? N
2)
What is the minimum angle the ladder must make with the floor to
not slip?
3)
A person with mass M = 62 kg now stands at the very top of the
ladder.

A 16.0-m uniform ladder weighing 490 N rests against a
frictionless wall. The ladder makes a 61.0° angle with the
horizontal.

A ladder of length 15.0 m and of mass 45.0kg is leaning against
a frictionless building wall. An85.0-kg person standing on the
ladder, 1.00 m from its top end, asks his friend to stand on one of
the lower rungs to prevent the ladder from slipping. If the
friend’s mass is 65.0 kg, where should he stand to keep the entire
system in equilibrium? The coefficient of friction between the
ladder and the ground is 0.300, and the angle that...
