Question

Block 1 of mass m is on top of block 2 of mass 5m as shown in the figure. Block 2 is on a horizontal smooth plane, and a rope can pull horizontally on block 2. The static and kinetic friction coefficients between the surfaces of the two blocks are 5/8 and 1/2 respectively. What is the resulting acceleration of block 2 if a force F=4mg with g being the acceleration of gravity is applied to the rope?

Basically the diagram is block 1 on top of block 2 (which is on the floor). There's a force being exerted on block 2 to the right from the rope. Thanks. :)

Answer #1

Block A, mass 250 g, sits on top of block B, mass 2.0 kg. The
coefficients of static and kinetic friction between blocks A and B
are 0.34 and 0.23, respectively. Block B sits on a frictionless
surface. What is the maximum horizontal force that can be applied
to block B, without block A slipping?

1. Two blocks are in static equilibrium
(a) If block A has a mass of 15 kg and coefficient of static
friction 0.2 find the maximum mass of block b
(b) If an extra 5 kg are added to B find the acceleration of A
and tension T in the rope. (coefficient of kinetic friction os
0.17)

A 3.0-kg block sits on top of a 5.0-kg block which is on a
horizontal surface. The 5.0-kg block is pulled to the right with a
force F⃗ . The coefficient of static friction between all
surfaces is 0.60 and the kinetic coefficient is 0.37.
a) What is the minimum value of F
needed to move the two blocks?
b) If the force is 10% greater than your answer for (a), what is
the acceleration of each block?

A
5.00 kg block sits on the floor at rest. You pull on a rope upwards
at an angle. The coefficient of static friction is 0.400 and the
coefficient of kinetic friction is 0.300. When you pull upwards
with a force of 20.0 N at an angle of 35.0°, what is the force of
friction on the box? What is the acceleration of the box?

A block with mass 10kg is on a ramp angled at 20 degrees above
the horizontal, attached via rope to another block hanging over the
top edge of the ramp (by a pulley), which is also 10kg. Wheat is
the coefficient of static friction needed so that the blocks do not
move? If there was no friction, what would the acceleration be?

Two wooden crates rest on top of one another. The smaller top
crate has a mass of m1 = 15 kg and the larger bottom
crate has a mass of m2 = 88 kg. There is NO friction
between the crate and the floor, but the coefficient of static
friction between the two crates is μs = 0.85 and the
coefficient of kinetic friction between the two crates is
μk = 0.66. A massless rope is attached to the lower...

As shown in Figure 1, a block (mass: 2.4 kg) is initially at
rest near the top of an inclined plane, oriented at a 25° angle
above the horizontal. The coefficients of static and kinetic
friction along the incline are 0.2 and 0.1, respectively.
(a) Just after the block is released from rest, draw a free-body
diagram for it. (Assume that the block is moving after being
released from rest.)
(b) Determine the magnitude of the normal force acting on...

Two blocks are positioned on surfaces, each inclined at the same
angle of 44.9 degrees with respect to the horizontal. The blocks
are connected by a rope which rests on a frictionless pulley at the
top of the inclines as shown, so the blocks can slide together. The
mass of the black block is 5.40 kg, and the coefficient of kinetic
friction for both blocks and inclines is 0.460. Assume static
friction has been overcome and that everything can slide....

Two blocks are positioned on surfaces, each inclined at the same
angle of 51.6 degrees with respect to the horizontal. The blocks
are connected by a rope which rests on a frictionless pulley at the
top of the inclines as shown, so the blocks can slide together. The
mass of the black block is 4.38 kg, and the coefficient of kinetic
friction for both blocks and inclines is 0.290. Assume static
friction has been overcome and that everything can slide....

A block with mass m1 = 8.8 kg is on an incline with
an angle θ = 27° with respect to the horizontal. For the first
question there is no friction between the incline and the
block.
1. When there is no friction, what is the magnitude of the
acceleration of the block?
2. Now with friction, the acceleration is measured to be only a
= 3.52 m/s2. What is the coefficient of kinetic friction
between the incline and the...
