A box of mass 14 kg sits at rest on a ramp that makes an angle
of 30 degrees with the horizontal. The coefficient of static
friction between the box and the ramp is 0.88. What is the
magnitude of the frictional force between the box and the ramp?

A 5 kg box sits on an inclined plane. If the coefficient of
static friction between the plane and the box is µs = 0.15. What is
the maximum angle θmax that the plane can be inclined without the
box sliding?

A 10kg block rests at the top of a frictionless ramp. The ramp
has an angle of inclination of 37 degrees with respect to the
horizontal surface, and a length of 10 meters. The coefficient of
static friction between the block and the ramp is .37, the
coefficient of kinetic friction is .25. a) Will the block move? b)
If so, how long will it take to reach the end of the ramp. c) If
so, how fast will it...

Ramp Angle is 37 degrees Mass is 5.0 kg Initial Velocity is 3.0
m/s Coefficient of Kinetic Friction is 0.6 Coefficient of Static
Friction is 0.8
Questions:
• What is value of each force that acts on the block?
•What is net force and acceleration of object?
• What distance does it travel along the ramp before
stopping?
• When block stops, will it stay at rest or start moving back
down?

A 1.2-kg block, travelling at 14.2-m/s, encounters a
ramp with a coefficient of kinetic friction of 0.15. The ramp is
tilted 31° above the horizontal. Use work and energy arguments to
answer the following.
How far along the ramp does the block travel?
Assume the coefficient of static friction is very
small and the block slides back down the ramp. What is its speed at
the bottom?

A 26.0 kg box of textbooks rests on a loading ramp that makes an
angle α with the horizontal. The coefficient of kinetic
friction is 0.40, and the coefficient of static friction is
0.50.
(a) As the angle α is increased, find the minimum angle
at which the box starts to slip.
(b) At this angle, find the acceleration once the box has begun
to move.
(c) At this angle, how fast will the box be moving after it has...

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.

A box of mass m = 10 kg sits on a table. The coefficient of
kinetic friction is 0.2 between the table and the box. A force of F
= 40 N is applied to it horizontally so that the box is moving
along the table. a) Calculate the work done by the friction force

What about the work done by the gravitational force? c) The...

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...

There is a variable amount of friction between a block of mass m
and a ramp at an angle θ above the horizontal. The kinetic and
static coefficients of friction are equal but vary as µ=Ax, where x
is measured along the ramp and x = 0 is the bottom of the ramp. The
block is sent up the ramp with an initial speed v0, and comes to a
stop somewhere on the ramp. In the following parts, take your...
