Question

The pulley shown below has a mass of 3.00 kg and radius R = 60.0 cm, and can be treated as a uniform solid disk that can rotate about its center. The block (which has a mass of m = 900 g) hanging from the string wrapped around the pulley is then released from rest. Use g = 10 m/s2. When the block has dropped through a distance of 2.00 m, what is the block's speed?

Answer #1

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.

A block (mass = 59.1 kg) is hanging from a massless cord that is
wrapped around a pulley (moment of inertia = 1/2MR2 kg ·
m2, where M = 6.9 kg is the mass of the pulley and R=1.3
m is its radius ), as the drawing shows. Initially the pulley is
prevented from rotating and the block is stationary. Then, the
pulley is allowed to rotate as the block falls. The cord does not
slip relative to the pulley...

Two blocks hang from either end of a massless rope that runs
over a pulley, treated as a thin solid disk, (An Atwood's Machine),
and are held in place. One block has a mass of 12.0 kg, the pulley
has a mass of 2.00 kg and radius 5.00 cm, and the other block's
mass is unknown. The blocks are released from rest, and after an
unspecified period of time, the block of known mass has descended
2.50 m and has...

A solid uniform disk of mass M = 9.6 kg and radius R = 21 cm
rests with its flat surface on a frictionless table (i.e., the axis
of the cylinder is perpendicular to the table.) The diagram shows a
top view. A string is wrapped around the rim of the disk and a
constant force of F = 10.8 N is applied to the string. The string
does not slip on the rim.

A
1.53kg bucket hangs on a rope wrapped around a pulley of mass
7.07kg and radius 66cm. This pulley is frictionless in its axle,
and has the shape of a solid uniform disk.
A. Explain conceptually why the moment of inertia of
this pulley is less than the moment of inertia of a hoop around its
center with the same mass and circumference as the
pulley.
B. What is the angular acceleration of the
pulley?
C. What is the acceleration...

A block (mass = 1.2 kg) is hanging from a massless cord that is
wrapped around a pulley (moment of inertia = 1.0 x 10-3 kg·m2), as
the figure shows. Initially the pulley is prevented from rotating
and the block is stationary. Then, the pulley is allowed to rotate
as the block falls. The cord does not slip relative to the pulley
as the block falls. Assume that the radius of the cord around the
pulley remains constant at a...

A block (mass = 3.0 kg) is hanging from a massless cord that is
wrapped around a pulley (moment of inertia = 1.2 x 10-3 kg·m2), as
the figure shows. Initially the pulley is prevented from rotating
and the block is stationary. Then, the pulley is allowed to rotate
as the block falls. The cord does not slip relative to the pulley
as the block falls. Assume that the radius of the cord around the
pulley remains constant at a...

A block (mass = 1.0 kg) is hanging from a massless cord that is
wrapped around a pulley (moment of inertia = 1.1 x 10-3
kg·m2), as the figure shows. Initially the pulley is
prevented from rotating and the block is stationary. Then, the
pulley is allowed to rotate as the block falls. The cord does not
slip relative to the pulley as the block falls. Assume that the
radius of the cord around the pulley remains constant at a...

A block (mass = 2.3 kg) is hanging from a massless cord that is
wrapped around a pulley (moment of inertia = 1.7 x 10-3 kg·m2), as
the figure shows. Initially the pulley is prevented from rotating
and the block is stationary. Then, the pulley is allowed to rotate
as the block falls. The cord does not slip relative to the pulley
as the block falls. Assume that the radius of the cord around the
pulley remains constant at a...

Consider an aluminum annular disk with an outer radius 63.2 mm
and inner radius 7.9 mm. The mass of the disk is 464 grams.
The disk is allowed to rotate on a frictionless table with the
rotation axis at its center. The disk has a small pulley rigidly
mounted at the top concentrically. The pulley's radius is 12.1 mm,
and the mass of the pulley is negligible. A string is wrapped
around the pulley, and a hanging mass of 19.3...
