A ladder whose length L is 12 m and mass m is 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...

A 14.0-m uniform ladder weighing 520 N rests against a frictionless wall. The ladder makes a 55.0degree angle with the horizontal. Find the horizontal and vertical forces the ground exerts on the base of the ladder when an 830-N firefighter has climbed 4.10 m along the ladder from the bottom. Horizontal Force If the ladder is just on the verge of slipping when the firefighter is 9.40 m from the bottom, what is the coefficient of static friction between ladder...

A uniform ladder stands on a rough floor and rests against a
frictionless wall as shown in the figure.
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 = 4.85 m,
a weight of
WL = 62.5 N,
