Question

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.

Answer #1

a 4.0 block starts from rest and slides down a plane
inclined at 60° horizonta l. The coefficient of kinetic friction
between the Surface and the block is 0.20. The work done by
friction on the block is?

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 79.0-kg skier starts from rest and slides down a 36.0-m
frictionless slope that is inclined at an angle of 15.0° with the
horizontal. Ignore air resistance.
(a) Calculate the work done by gravity on the skier and the work
done by the normal force on the skier. Work done by gravity? Work
done by normal force?
(b) If the slope is not frictionless so that the skier has a
final velocity of 4 m/s, calculate the work done by...

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...

A construction worker pushes on a 10 kg crate down an inclined
plane that is 7.0 m long and is inclined at an angle of 20 degrees
to the horizontal. As a result, the crate slides down the entire
length of the plane with a constant speed of 3.0 m/s. Suppose that
the worker pushes directly on the crate in a direction parallel to
the incline with a force of 50 N for the entire length of the
plane. A)...

A 2.70-kg block starts from rest at the top of a 30.0° incline
and slides a distance of 1.90 m down the incline in 1.20 s.
(a) Find the magnitude of the acceleration of the block.
(m/s)^2
(b) Find the coefficient of kinetic friction between block and
plane.
(c) Find the friction force acting on the block.

A
box kg meters with constant speed on a rough inclined plane whose
surface is 30 ° with the horizontal. What is the magnitude of the
work done by the friction force?
A
box of mass M = 5 kg slides 10 meters with constant speed on a
rough inclined plane whose surface is 30 ° with the horizontal.
What is the magnitude of the work done by the friction force?

A box with 10 kg of mass slides down an inclined plane that is
1.7 m high and 3.5 m long. Due to friction the box reaches 3.0 m/s
at the bottom of the inclined plane. Beyond the inclined plane lies
a spring with 650 N/m constant. It is fixed at its right end. The
level ground between the incline and the spring has no friction
The box compressed the spring, got pushed back towards the
incline by the spring....

A box with 11 kg of mass slides down an inclined plane that is
2.0 m high and 3.5 m long. Due to friction the box reaches 3.3 m/s
at the bottom of the inclined plane. Beyond the inclined plane lies
a spring with 650 N/m constant. It is fixed at its right end. The
level ground between the incline and the spring has no friction
The box compressed the spring, got pushed back towards the
incline by the spring....
