Question

The pulley in the following figure is a uniform disk with the
radius 0.160 m and the mass M=4kg. The rope does not slip on the
pulley rim. Use energy methods to calculate the speed of the
m_{2} = 9 kg block just before it strikes the floor.(
m_{1}= 2.00 kg, g=10m/s^{2})

Answer #1

The pulley in the following figure is a uniform disk with the
radius 0.160 m and the mass M=4kg. The rope does not slip on the
pulley rim. Use energy methods to calculate the speed of the
m2 = 9 kg block just before it strikes the floor.(
m1= 2.00 kg, g=10m/s2)

The pulley is a uniform cylinder with mass m3 = 0.400 kg and
radius R= 4.00 cm, the other two masses are m1 = 2.00 kg and m2 =
1.00 kg, and α = 35.0 degrees. Assume the rope is massless, there
is no slipping of the rope on the pulley, there is no friction
between m1 and the incline, and the incline position is fixed.
(a)
What is the acceleration of m1 and m2 (both magnitude and
direction)? What...

A 10 kg pulley with radius 1.0 m has an angular acceleration of
4.0 rad/s2 due to a wooden block hanging from a rope wound around
the pulley. What is the mass of the block (in kg)? Consider the
pulley to be a uniform disk.

Two objects are connected to a rope, and the rope is hung over a
pulley connected to the ceiling, as shown in the figure below.
Two objects, labeled m1 and
m2, are connected to a rope which is hung over
a pulley connected to the ceiling. The pulley is of mass M
and radius R. An object labeled m1
hangs suspended off the surface on the left side of the pulley. An
object m2 is on the right side of...

Two masses, mA = 32.0 kg and mB = 41.0 kg are connected by a
rope that hangs over a pulley (as in the figure(Figure 1)). The
pulley is a uniform cylinder of radius R = 0.316 m and mass 3.4 kg
. Initially, mA is on the ground and mB rests 2.5 m above the
ground. a.If the system is now released, use conservation of energy
to determine the speed of mB just before it strikes the ground.
Assume...

A hanging weight, with a mass of m1 = 0.355
kg, is attached by a rope to a block with mass
m2 = 0.845 kg as shown in the figure below. The
rope goes over a pulley with a mass of M = 0.350 kg. The
pulley can be modeled as a hollow cylinder with an inner radius of
R1 = 0.0200 m, and an outer radius of
R2 = 0.0300 m; the mass of the spokes is
negligible. As...

A block with mass m1 hangs from a rope that is extended over an
ideal pulley and attached to a second block with mass m2 that sits
on a ledge. The second block is also connected to a third block
with mass m3 by a second rope that hangs over a second ideal pulley
as shown in the figure below. If the friction between the ledge and
the second block is negligible, m1 = 2.60 kg, m2 = 4.00 kg,...

Consider the following situation as pictured in the figure. A
block slides on a friction-less table dragged by a rope that goes
over a pulley and from which a weight is hanged. The pulley can be
considered a disk. Its mass is 5 Kg, and its radius is 1 m. The
block has a mass of 2 Kg and the hanging weight has a mass of 1 Kg.
m1=2Kg m2=1Kg A. First write the free body diagram for each mass...

In the figure below, the hanging object has a mass of
m1 = 0.370 kg; the sliding block has a mass of
m2 = 0.900 kg; and the pulley is a hollow
cylinder with a mass of M = 0.350 kg, an inner radius of
R1 = 0.020 0 m, and an outer radius of
R2 = 0.030 0 m. Assume the mass of the spokes
is negligible. The coefficient of kinetic friction between the
block and the horizontal surface...

A 170-kg merry-go-round in the shape of a uniform, solid,
horizontal disk of radius 1.50 m is set in motion by wrapping a
rope about the rim of the disk and pulling on the rope. What
constant force would have to be exerted on the rope to bring the
merry-go-round from rest to an angular speed of 0.600 rev/s in 2.00
s? (State the magnitude of the force.)
