A window washer weighing 788.3 N is standing on a scaffold supported by a vertical rope at each end. The scaffold weighs 294.9 N and is 5.486 m long. What is the force in each rope when the window washer stands 1.62 m from one end?

A window washer on a scaffold hoists the scaffold up the side of
a building by pulling down on a rope that runs over a pulley and
connects back to the top of the scaffold. The combined mass of the
worker and the scaffold is 100kg, and the washer pulls on the rope
with a force of 800N. What is the acceleration of the scaffold?

A vertical spring with k = 490 N/m is standing on the
ground. You are holding a 5.8 kg block just above the spring, not
quite touching it.
(a) How far does the spring compress if you let go of the block
suddenly?
m
(b) How far does the spring compress if you slowly lower the block
to the point where you can remove your hand without disturbing
it?
0.116 m is the answer I got and know how to...

A 1220-N uniform beam is hinged at a vertical wall at one end
and is supported by a cable that is attached to the beam at the
other end. A 200-kg load hangs at the end of the beam. The lower
end of the beam makes an angle of 30° above the horizontal, while
the supporting cable is attached to the wall at an angle of 40°, as
shown.
(a) Calculate the magnitude of the tension in the supporting
cable....

A block weighing 20 N oscillates at one end of a vertical spring
for which k = 140 N/m; the other end of the spring is
attached to a ceiling. At a certain instant the spring is stretched
0.20 m beyond its relaxed length (the length when no object is
attached) and the block has zero velocity. (a)
What is the net force on the block at this instant? What are the
(b) amplitude and (c) period of
the resulting...

A uniform 5-m long ladder weighing 80 N leans against a
frictionless vertical wall. The foot of the ladder is 1 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?

A window washer with a mass of 63.0 kg stands a distance, D =
0.600 m, from the left end of a plank of length, L= 2.10 m, with a
mass of 19.0 kg. The plank is hung on two cables as shown. Find
T2, the tension in the right cable.

An ant with mass m kg is standing peacefully on top of a horizontal stretched rope. The rope has mass per unit length 2.88 kg/m and is under tension 35 N. Without warning your nemesis Throckmorton starts a sinusoidal transverse wave of wavelength 0.85 m propagating along the rope. The motion of the rope is in the vertical plane. What minimum wave amplitude will make the ant become momentarily weightless? Assume that the mass of the ant is so small...

It is past midnight and Lucy is sliding down a rope from her
third window to meet her friend in order to “work on physics
homework.” AS she slides down the rope faster and faster, she
becomes worried and gradually tightens her grip on the rope. Thus,
the tension in the rope slowly increases, and when it becomes equal
to Lucy’s weight.

Two waves traveling in opposite directions on a
stretched rope interfere to give the standing wave described by the
following wave function:
y(x,t) = 4 sin(2πx) cos(120πt),
where, y is in centimetres, x is in meters, and t is
in seconds. The rope is two meters long, L = 2 m, and is fixed at
both ends.
The distance between two successive antinodes is:
d_AA = 0.25 m
d_AA = 0.15 m
d_AA = 1 m
d_AA = 0.5m
d_AA...

Two waves traveling in opposite directions on a
stretched rope interfere to give the standing wave described by the
following wave function:
y(x,t) = 4 sin(2πx) cos(120πt),
