Question

An Atwood machine consists of two masses, mA = 64 kg and mB = 73 kg , connected by a massless inelastic cord that passes over a pulley free to rotate (Figure 1). The pulley is a solid cylinder of radius R = 0.45 m and mass 5.0 kg . [Hint: The tensions FTA and FTB are not equal.] Part A Determine the acceleration of each mass. Express your answer to two significant figures and include the appropriate units. part b: What % error would be made if the moment of inertia of the pulley is ignored? Express your answer using two significant figures.

Answer #1

An Atwood machine consists of two masses, mA = 65 kg and mB = 75
kg , connected by a massless inelastic cord that passes over a
pulley free to rotate. The pulley is a solid cylinder of radius R =
0.45 m and mass 6.0 kg. Determine the acceleration of each mass

Two masses, mA = 32.0 kg and mB = 41.0 kg are connected by a
rope that hangs over a pulley (as in the figure(Figure 1)). The
pulley is a uniform cylinder of radius R = 0.316 m and mass 3.4 kg
. Initially, mA is on the ground and mB rests 2.5 m above the
ground. a.If the system is now released, use conservation of energy
to determine the speed of mB just before it strikes the ground.

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

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.

An Atwood Machine consists of two masses m1 and
m2 attached to each other by a single massless string
passing over a cylindrical pulley of mass M without slipping. The
masses are released from rest, and allowed to accelerate until each
has moved a distance h = 1.6 m. Assuming that upwards is positive,
rank the velocity of m2 (from most negative to most
positive) at this moment for the following cases:
Case A: m1 = 11 kg,...

An Atwood's machine consists of blocks of masses
m1 = 12.0 kg

m2, are connected to a cord which is hung...

Two balls, of masses MA= 40g and MB= 60g are suspended. The
lighter ball is pulled away to a 66 degree angle with the vertical
and released. The two balls stick and move together (collision is
completely inelastic). (length of suspension is 30cm)
1. What is the velocity of the lighter ball just before
impact?
2. What is the velocity of the combined mass after the
collison?
3. What will be the maximum angle reached by the combined mass
(theta...

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 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...

Two boxes, masses 10 kg and 8 kg, are attached to the end of a
massless rod which pivots at 2 m from the left corner and held
above the ground. The 10 kg mass is attached to the left end. The
total length of the rod is 10 m.
1. Find the moment of inertia of the system around the pivoted
point.
2. Find the net torque of the system when the massless rod is
horizontal.
3. Calculate the...
