Question

- A solid cylinder of mass M and radius 2R rests on a horizontal table. A cord is attached by a yoke to a frictionless shaft that passes through the cylinder, so that it can rotate on the shaft. The cord passes through a disk-shaped pulley of mass M and radius R, which is mounted on a frictionless shaft that passes through its center. A block of mass M is suspended from the free end of the thread. The thread does not slip on the pulley, and the cylinder rolls without slipping on the table. If the system is released from rest, what acceleration down will the block have?

A textbook of mass 2.09 kg rests on a frictionless, horizontal
surface. A cord attached to the book passes over a pulley whose
diameter is 0.130 m , to a hanging book with mass 3.02 kg . The
system is released from rest, and the books are observed to move a
distance 1.12 m over a time interval of 0.790 s .
What is the tension in the part of the cord attached to the
textbook?

A hanging weight, with a mass of m1 = 0.365
kg, is attached by a cord to a block with mass
m2 = 0.815 kg as shown in the figure below. The
cord 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 textbook of mass 1.91 kg rests on a frictionless, horizontal
surface. A cord attached to the book passes over a pulley whose
diameter is 0.200 m, to a hanging book with mass 3.03 kg. The
system is released from rest, and the books are observed to move a
distance 1.19 mm over a time interval of 0.790 s.

A uniform cylinder of mass 100 kg and radius 50 cm is mounted so
it is free to rotate about a fixed, horizontal axis that passes
through the centers of its circular ends. A 10-kg block is hung
from a massless cord that is wrapped around the cylinder’s
circumference. When the block is released, the cord unwinds and the
block accelerates downward. a) What is the block’s
acceleration?

A uniform spherical shell of mass M = 17.0 kg and radius R =
0.310 m can rotate about a vertical axis on frictionless bearings
(see the figure). A massless cord passes around the equator of the
shell, over a pulley of rotational inertia I = 0.210 kg·m2 and
radius r = 0.100 m, and is attached to a small object of mass m =
1.50 kg. There is no friction on the pulley's axle; the cord does
not slip...

A uniform spherical shell of mass M = 3.2 kg and radius
R = 7.8 cm can rotate about a vertical axis on
frictionless bearings (see figure below). A massless cord passes
around the equator of the shell, over a pulley of rotational
inertia I = 3.0 ? 10?3 kg · m2 and
radius r = 5.0 cm, and is attached to a small object of
mass m = 0.60 kg. There is no friction on the pulley's
axle; the...

A block of mass 1.970 kg is free to slide on a
frictionless, horizontal surface. A cord attached to the block
passes over a pulley whose diameter is 0.150 m , to a
hanging book with mass 3.030 kg . The system is released
from rest, and both the book and the block are observed to move a
distance 1.19 m over a time interval of
0.780 s ; at the instant at which that distance is
measured, the book is still moving downwards and...

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...
