Question

Two blocks (m_{1=}5.5kg, m_{2}_{=}7.2kg
) are connected by a string that passes through a massless pulley
as shown in the Figure. The first block with mass
m_{1} **slides up** the inclined
plane when the system is released. The inclined plane makes an
angle θ = 31* ^{0}* with the
horizontal and the kinetic friction coefficient between the
inclined plane and m

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 θ1=46.5∘ with
coefficient of kinetic friction μ1=0.205.
M2 has a mass of 6.05 kg and is on an incline of θ2=33.5∘ with
coefficient of kinetic friction μ2=0.105.
The two‑block system is in motion with the block of mass M2
sliding down the ramp.

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.

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...

In the figure, two blocks are shown with an inclined plane. The
two blocks are connected by a massless string strung over a
massless pulley. The mass of Block #1 is 3.57 kg and that
of Block #2 is 11.0 kg. The angle θ of the
incline is 43.0 degrees. The plane is NOT smooth and has a
coefficient of static friction of 0.570 and a coefficient of
kinetic friction of 0.240.
Taking the positive direction to be up the...

Two blocks are connected by a string that passes over a
massless, frictionless pulley, as shown in the figure. Block A,
with a mass mA = 2.00 kg, rests on a ramp
measuring 3.0 m vertically and 4.0 m horizontally. Block B hangs
vertically below the pulley. Note that you can solve this exercise
entirely using forces and the constant-acceleration equations, but
see if you can apply energy ideas instead. Use g = 10
m/s2. When the system is released...

Two blocks are connected by a massless string that runs across a
frictionless pulley with a mass of 5.00 kg and a radius of 10.0 cm.
The first block with an unknown mass of m1 sits on a horizontal
surface and is also connected to a spring with a spring constant of
k = 250 N/m. The coefficient of kinetic friction between the first
block and the surface is 0.400. The second block with a mass of m2
= 6.00...

Two blocks with masses m1 = 1.10 kg and m2 = 3.50 kg are
connected by a massless string. They are released from rest. The
coefficent of kinetic friction between the upper block and the
surface is 0.440. Assume that the pulley has a negligible mass and
is frictionless, and calculate the speed of the blocks after they
have moved a distance 68.0 cm.

In the figure, the two blocks are attached by a massless rope
over a frictionless pulley, and block M1 slides on the table
without friction. The masses of the blocks are: M1 = 7.90kg and M2
= 3.70kg. Calculate the tension in the rope. ( g = 9.80
m/s2)

Two packing crates of masses
m1 = 10.0 kg
and
m2 = 4.70 kg

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 masses are connected by a massless string and a frictionless
pulley. The masses of the blocks are; m1=500 g and m2= 150g. The

the string?
