Question

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.

**Find the magnitude a2 of the acceleration of M2 down the
incline.**

Answer #1

Acceleration of M 2 = 1.02 m/s^2

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 (m1=5.5kg, m2=7.2kg
) are connected by a string that passes through a massless pulley
as shown in the Figure. The first block with mass
m1 slides up the inclined
plane when the system is released. The inclined plane makes an
angle θ = 310 with the
horizontal and the kinetic friction coefficient between the
inclined plane and m1 is
=0.35. Take g=10m/s2 Find
the speed of the block with mass m2 after it travels
h=5.6m.

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.

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 attached to opposite ends of a string that passes
over a massless, frictionless pulley (see the figure). Block ? of
mass 10.0 kg lies on a 60.0° incline with a coefficient of friction
of 0.500, and block ? of mass 1.00 kg is attached to a vertical
spring of force constant 200 N/m. The blocks are initially at rest
with the spring at equilibrium. Find the maximum height that the
block ? rises.

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...

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

Two masses

Objects with masses m1 = 12.0 kg and
m2 = 8.0 kg are connected by a light string

when the system starts from rest, m2 falls 1.00
m in 1.48 s, 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

coefficient of static friction of 0.570 and a coefficient of
kinetic friction of 0.240.
