Question

7) A block of mass *m*_{1} = 38 kg on a
horizontal surface is connected to a mass *m*_{2} =
21.6 kg that hangs vertically as shown in the figure below. The two
blocks are connected by a string of negligible mass passing over a
frictionless pulley. The coefficient of kinetic friction between
*m*_{1} and the horizontal surface is 0.24.

(a) What is the magnitude of the acceleration (in
m/s^{2}) of the hanging mass?

Answer: m/s^{2}

(b) Determine the magnitude of the tension (in N) in the cord above the hanging mass.

Answer: N

Answer #1

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...

A block of mass m1 = 3.27 kg on a frictionless plane inclined at
angle θ = 26.2° is connected by a cord over a massless,
frictionless pulley to a second block of mass m2 = 2.60 kg hanging
vertically (see the figure). (a) What is the acceleration of the
hanging block (choose the positive direction down)? (b) What is the
tension in the cord?

m1 = 2.2 kg block slides on a frictionless horizontal surface
and is connected on one side to a spring (k = 45 N/m) as shown in
the figure above. The other side is connected to the block m2 = 4
kg that hangs vertically. The system starts from rest with the
spring unextended.
a) What is the maximum extension of the spring?
m
a) What is the speed of block m2 when the extension is 45 cm?

A block with mass m1 hangs from a rope that is extended over an
ideal pulley and attached to a second block with mass m2 that sits
on a ledge. The second block is also connected to a third block
with mass m3 by a second rope that hangs over a second ideal pulley
as shown in the figure below. If the friction between the ledge and
the second block is negligible, m1 = 2.60 kg, m2 = 4.00 kg,...

Two packing crates of masses
m1 = 10.0 kg
and
m2 = 4.70 kg
are connected by a light string that passes over a frictionless
pulley as in the figure below. The 4.70-kg crate lies on a smooth
incline of angle 35.0°. Find the following.
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....

Two blocks of mass m1 = 9.20 kg and m2 are connected by a light
string. When a horizontal force F = 105 N is applied to m1 as shown
in the figure below, the acceleration of the system is 3.20 m/s2
towards the left and the tension in the string connecting the two
blocks is 62.0 N. The blocks are moving on a rough surface with an
unknown coefficient of kinetic friction. Determine the coefficient
of kinetic friction between...

A mass m1 is connected by a light string that passes
over a pulley of mass M to a mass m2 sliding on a
frictionless horizontal surface as shown in the figure. There is no
slippage between the string and the pulley. The pulley has a radius
of 25.0 cm and a moment of inertia of ½ MR2. If
m1 is 1.00 kg, m2 is 2.00 kg, and M is 4.00
kg, then what is the tension in the string...

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...

In the figure below the two blocks are connected by a string of
negligible mass passing over a frictionless pulley.
m1 = 10.0 kg and m2 = 5.50
kg and the angle of the incline is θ = 39.0°. Assume that
the incline is smooth. (Assume the +x direction is down
the incline of the plane.)
(a)
With what acceleration (in m/s2) does the mass
m2 move on the incline surface? Indicate the
direction with the sign of your answer....

An object with mass m1 = 3.70 kg, rests on a
frictionless horizontal table and is connected to a cable that
passes over a pulley and is then fastened to a hanging object with
mass m2 = 10.8 kg, as shown in the figure.
Two objects labeled m1 and
m2 are attached together by a cable.
Object m1 lies on a horizontal table with
the cable extending horizontally from its right side.
The cable extends horizontally from the right side...
