Question

Two objects with masses of *m*_{1} = 3.90 kg and
*m*_{2} = 5.70 kg are connected by a light string
that passes over a frictionless pulley, as in the figure below.

A string passes over a pulley which is suspended from a
horizontal surface. A circular object of mass
*m*_{1} and a rectangular object of
*m*_{2} are, respectively, attached to the left and
right ends of the string.

(a) Determine the tension in the string. (Enter the magnitude
only. Due to the nature of this problem, do not use rounded
intermediate values in your calculations—including answers
submitted in WebAssign.)

N

(b) Determine the acceleration of each object. (Enter the magnitude
only.)

m/s^{2}

(c) Determine the distance each object will move in the first
second of motion if both objects start from rest.

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...

m in 1.54 s, determine the coefficient of kinetic friction between
m1 and the table.

Two crates are connected to each other by a string that passes
over a pulley, which is attached to the top corner of a wedge. The
crate of mass m1 hangs freely below the pulley....

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...

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...

An Atwood's machine consists of two masses, m1 and m2, connected
by a string that passes over a pulley. If the pulley is a disk of
radius R and mass M, find the acceleration of the masses.
Express your answer in terms of the variables m1, m2, R,
M, and appropriate constants.

Two blocks with masses M1 and M2 are connected by a massless
string that passes over a massless pulley as shown. M1 has a mass
of 2.25 kg and is on an incline of 49.5° with coefficient of
kinetic friction ?1 = 0.205. M2 has a mass of 5.45 kg and is on an
incline of 31.5° with coefficient of kinetic friction ?2 = 0.105.
Find the magnitude of the acceleration of M2 down the incline.

An
Atwood's machine consists of two masses, m1 and m2, connected by a
string that passes over a pulley. If the pulley has radius and
moment of inertia 1/2 MR^2 about its axle. Determine the
acceleration if masses m1 and m2. Compare the situation in which
moment of inertia is ignored

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...

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...
