Question

A m1 = 15.4 kg mass and a m2 = 11.7 kg mass are suspended by a
pulley that has a radius of R = 10.3 cm and a mass of M = 2.84 kg.
The cord has a negligible mass and causes the pulley to rotate
without slipping. The pulley rotates without friction. The masses
start from rest *d* = 2.72 m apart. Treating the pulley as a
uniform disk, determine the speeds of the two masses as they pass
each other.

Answer #1

A m1 = 16.6 kg mass and a
m2 = 10.1 kg mass are suspended by a pulley
that has a radius of R = 12.4 cm and a mass of M
= 2.60 kg, as seen in the figure below. The cord has a negligible
mass and causes the pulley to rotate without slipping. The pulley
rotates without friction. The masses start from rest d =
3.30 m apart. Treating the pulley as a uniform disk, determine the
speeds...

A m1 = 13.5 kg object and a
m2 = 10.0 kg object are suspended, joined by a
cord that passes over a pulley with a radius of 10.0 cm and a mass
of 3.00 kg (Fig. P10.46). The cord has a negligible mass and does
not slip on the pulley. The pulley rotates on its axis without
friction. The objects start from rest 3.00 m apart. Treating the
pulley as a uniform disk,determine the speeds of the two objects...

An Atwood's machine consists of blocks of masses
m1 = 12.0 kg
and
m2 = 22.0 kg
attached by a cord running over a pulley as in the figure below.
The pulley is a solid cylinder with mass
M = 7.60 kg
and radius
r = 0.200 m.
The block of mass m2 is allowed to drop, and
the cord turns the pulley without slipping.
Two objects, blocks labeled m1 and
m2, are connected to a cord which is hung...

Objects with masses m1 = 12.0 kg and
m2 = 8.0 kg are connected by a light string
that passes over a frictionless pulley as in the figure below. If,
when the system starts from rest, m2 falls 1.00
m in 1.48 s, determine the coefficient of kinetic friction between
m1 and the table.
Express the friction force in terms of the coefficient of kinetic
friction. Obtain an expression for the acceleration in terms of the
masses and the...

The pulley in (Figure 1) is suspended by a cord
C.Suppose that m1 = 1.5 kg and m2 = 3.5
kg .
Determine the tension in the cord that supports the pulley
C after the masses are released and before one hits the
ground. Ignore the mass of the pulley and cords.

Two blocks of mass m1 = 2 kg and m2 = 1 kg are suspended over a
pulley of mass M with a string of neglible mass. The pulley is a
solid cylinder of radius R = 4 cm. The string does not slip on the
pulley, which is a solid cylinder. The magnitude of downward
accleration of mass m1 is measured to be a = g/4.
A) Write down Newton's second law for m1, m2, and M using the...

An Atwood's machine consists of blocks of masses m1 = 13.0 kg
and m2 = 19.0 kg attached by a cord running over a pulley as in the
figure below. The pulley is a solid cylinder with mass M = 9.20 kg
and radius r = 0.200 m. The block of mass m2 is allowed to drop,
and the cord turns the pulley without slipping.
(a) Why must the tension T2 be greater than
the tension T1?
This answer has...

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 mass (M1=5.0kg) is connected by a light cord to a mass
(M2=4.0kg) which slides on a smooth frctionless surface. The
pulley( a solid disk r=0.20m) rotates about a frictionless axle.
The accleration of M2 is 3.5 m/s^2. What is the mass of the
pulley?

Two masses, m1= 1.00 kg and m2= 2.00 kg,
are attached to the ends of a light cord, which passes over a
frictionless pulley in the shape of a uniform disk of mass 3.00 kg.
How long does it take the 2.00 kg mass to fall a vertical distance
of 1.00 m? What is the tension of either side of the pulley?
(Answers: t= 0.958 sec; T1= 12.0 N; T2=
15.2 N I just need help with the steps for...
