A block of mass M1 resting on a 20.8° slope is shown. The block has
coefficients of friction μs = 0.792 and μk = 0.313 with the
surface. It is connected via a massless string over a massless,
frictionless pulley to a hanging block of mass M2 = 2.02 kg.

(a) What is the minimum mass M1 that will remain stationary
and not slip?

(b) If this minimum mass is nudged ever so slightly, it will
start being pulled up the incline. What magnitude of acceleration
will it have?

A block m1= 0.5kg slides on a plane inclined at 300 to the
horizontal. It is attached to a string which runs over a pulley and
has a mass m2=0.2kg hanging at the other end. The coefficients of
friction between the block m1 and the plane are: μs = 0.4 and μk =
0.3 . Assume that at t=0s, the block m1 is moving down the incline.
Refer to this moment and: a) Draw FBD for both blocks. b) Write...

A mass m1 = 1 kg on a horizontal table is pulled by a string
looped over a massless frictionless pulley and attached to another
hanging mass m2. The coefficient of kinetic friction between the
table and mass m1 is 0.5 and the coefficient of static friction is
0.6.
a) What is the minimum mass m2 that will start both masses
moving?
b) What is the acceleration of the system with this minimum
mass?

The system shown in the figure below consists of a mass M =
4.1-kg block resting on a frictionless horizontal ledge. This block
is attached to a string that passes over a pulley, and the other
end of the string is attached to a hanging m = 2.4-kg block. The
pulley is a uniform disk of radius 8.0 cm and mass 0.60 kg.
(a) What is the acceleration of each block?
acceleration of M = 4.1 kg
acceleration of m...

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?

Part A- a box (mass 12.1 kg) sits on a
rough incline that makes an angle α
= 30.2o with the horizontal. A massless string is
tied to the box, runs parallel to the incline, passes over a
massless, frictionless pulley, and is tied to mass M
hanging on the other end. Assume μs = 0.335 is the
coefficient of static friction between the box and the surface of
the plane. Find the maximum value of
M, in kg, for...

A hanging weight, with a mass of m1 = 0.370
kg, is attached by a string to a block with mass
m2 = 0.850 kg as shown in the figure below. The
string 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...

3. Two blocks of mass m and M = 10.0 ks are connected via a
massless and frictionless pully with a configuration as shown. The
coefficient of static friction is μs = 0.7 between block and
surface, while the coefficient of kinematic fraction is μk =
0.4.
1) Draw free-body diagram for both block (identify all the
forces on the two objects
2) What is the maximum mass m for the hanging block so that no
sliding occurs?
3) If...

A m1 = 1.7 kg box is on a frictionless θ = 43 ∘ slope and is
connected via a massless string over a pulley of mass M = 1.3 kg
and radius R = 0.6 m to a hanging m2 = 9.3 kg weight. The
coefficient of kinetic friction between the ramp and m1 is 0.2.
The boxes are released from rest. Calculate the work done on m1 by
kinetic friction as m2 drops by a distance of 1.7...

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...
