Question

A block is at rest on an inclined plane whose elevation can be
varied. The coefficient of static friction is
μ_{s}= 0.36, and the coefficient of kinetic
friction is μ_{k} = 0.16. The angle of elevation θ
is increased slowly from the horizontal.

At what value of θ does the block begin to slide (in
degrees)?

What is the acceleration of the block?

Answer #1

A 5.00-kg 5.00-kg block is sent up a ramp inclined at an angle
?= 25.0 ∘ θ=25.0∘ from the horizontal. It is given an initial
velocity ? 0 =15.0 m/s v0=15.0 m/s up the ramp. Between the block
and the ramp, the coefficient of kinetic friction is ? k =0.50
μk=0.50 and the coefficient of static friction is ? s =0.60.
μs=0.60. What distance ? D along the ramp's surface does the block
travel before it comes to a stop?

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.

In the figure, a 5.40 kg block is sent sliding up a plane
inclined at θ = 37.0° while a horizontal force
of magnitude 50.0 N acts on it. The coefficient of
kinetic friction between block and plane is 0.330. What are the
(a) magnitude and (b) direction
(up or down the plane) of the block's acceleration? The block's
initial speed is 4.30 m/s. (c) How far up the
plane does the block go? (d) When it reaches its

A 1 kg block, starting from rest, slides down a 22 degree
inclined plane that is .55m tall. At the bottom, the 1 kg block
collides with a 3 kg block. The two blocks stick together and slide
.52 m on a friction less horizontal surface for .52 sec. What is
the speed of the 1kg block before it collides with the 3 kg block?
What is the acceleration of the 1kg block as it travels down the
inclined plane?...

A
10 kg block is launched up a plane inclined at a 15° angle. The
initial speed of the block is 5 m/s.
a) Using Newton's laws of motion and the equations of
kinematics, calculate how far up the inclined plane does the block
slide in the absence of friction?
b) Using work and energy, answer the question in part (a) in
the presence of friction, taking the coefficient of kinetic
friction between the block and the surface to be...

A box of books is initially at rest a distance D =
0.493 m from the end of a wooden board. The coefficient of static
friction between the box and the board is μs = 0.357,
and the coefficient of kinetic friction is μk = 0.280.
The angle of the board is increased slowly, until the box just
begins to slide; then the board is held at this angle. Find the
speed of the box as it reaches the end...

A block with mass m1 = 8.8 kg is on an incline with
an angle θ = 40° with respect to the horizontal. For the first
question there is no friction, but for the rest of this problem the
coefficients of friction are: μk = 0.38 and
μs = 0.418.
1. When there is no friction, what is the magnitude of the
acceleration of the block?
2. Now with friction, what is the magnitude of the acceleration
of the block...

A 40.0N box begins to slide from rest through a plane inclined at 25 degrees (with respect to the horizontal) and which has a length of 7.00m. The coefficient of kinetic friction between the box and the plane is 0.138. Determine:
a) the kinetic energy of the box when it reaches the end of the inclined plane
b) the kinetic friction force

A block lies on an inclined plane with an angle of elevation
theta. The inclined plane is frictionless, and the plane is
accelerated to the left such that the block's height remains
constant. What is the net force on the block?

Consider an inclined plane at an angle of 40.0°, with a kinetic
coefficient of friction of 0.350 and a static coefficient of
friction of 0.450. A block with mass of 50.0 kg is on the incline
and initially at rest. A force of 535 N, parallel to the incline,
pushes the block a distance of 10.0 m up the incline. Do the
following:
a) Determine the speed of the object at the end of this
displacement using Newton’s Laws of...
