Question

A 4.00 kg stone is tied to a thin, light wire wrapped around the outer edge of the uniform 10.0 kg cylindrical pulley shown in the figure below (Figure 1). The inner diameter of the pulley is 60.0 cm , while the outer diameter is 1.00 m . The system is released from rest, and there is no friction at the axle of the pulley.

a) Find the acceleration of the stone.

b) Find the tension in the wire.

c) Find the angular acceleration of the pulley.

A stone is suspended from the free end of a wire that is wrapped
around the outer rim of a pulley, as shown in the figure (see the
figure (Figure 1) ). The pulley is a uniform disk with mass 12.0kg
and radius 31.0cm and turns on frictionless bearings. You measure
that the stone travels a distance 12.7m during a time interval of
2.00s starting from rest.

A stone is suspended from the free end of a wire that is wrapped
around the outer rim of a pulley, similar to what is shown in
(Figure 1). The pulley is a uniform disk with mass 13.0 kg and
radius 29.0 cm and turns on frictionless bearings. You measure that
the stone travels a distance 12.4 m during a time interval of 3.00
s starting from rest.

A 90 kg mass is tied to a massless rope wrapped around a solid
cylindrical drum, mounted on a frictionless horizontal axle. When
the mass is released, it falls with acceleration 3.4 m/s2 .
a. Find the rope tension. Express your answer in
newtons.
b. Find the drum's mass.

A 12.0-kg box resting on a horizontal, frictionless surface is
attached to a 5.00-kg weight by a thin, light wire that passes
without slippage over a frictionless pulley (the figure (Figure 1)
). The pulley has the shape of a uniform solid disk of mass 2.00 kg
and diameter 0.520 m .
Part A
After the system is released, find the horizontal tension in the
wire.
Part B
After the system is released, find the vertical tension in the
wire....

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

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

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...
