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 16.1 kg box is at rest on an inclined plane. The plane makes
an angle of 39.3 with the horizontal. How much is the friction
force (in Newtons) on the plane that holds it at rest?

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?...

2. A block slides down a plane inclined at 35o with
respect to the horizontal, with coefficient of kinetic friction
0.2. Find the ratio of the time taken to slide down the plane
starting from rest, compared to the time it would take to slide
down the plane if it were frictionless.
3. A 20 kg block slides frictionlessly down an inclined plane
that is 2.8 m long and 1.2 m high. A person pushes up against the
block, parallel...

A block is at rest on an inclined plane whose elevation can be
varied. The coefficient of static friction is
μs= 0.36, and the coefficient of kinetic
friction is μk = 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?

The 50-kg crate is resting on an inclined plane 15 deg. with
respect to the horizontal. The coefficient of static friction is
0.2 and coefficient of kinetic friction is 0.15. If a force P,
acting upward and parallel to the inclined plane is applied to the
crate, determine the resulting acceleration of the crate if
P=150N.

A 5.000 kg mass starts from rest and slides down on an inclined
plane that is 5 degrees above the horizontal. If friction causes
the body to accelerate at 20%, determine magnitude and direction of
friction force.

A
7.00-kg box sits on a ramp that is inclined at 36.3 ∘ above the
horizontal. The coefficient of kinetic friction between the box and
the ramp is 0.31.
What horizontal force is required to move the box up the
incline with a constant acceleration of
4.30 m/s2 ?

The initial speed of a 2.58-kg box traveling up a plane inclined
37° to the horizontal is 4.55 m/s. The coefficient of kinetic
friction between the box and the plane is 0.30.
(a) How far along the incline does the box travel before coming to
a stop?
---m
(b) What is its speed when it has traveled half the distance found
in Part (a)?
---m/s
