Question

A block is at the base of a ramp of angle 35. The
ramp is 5 m long and has coefficients of static and kinetic
friction of 0.6 and 0.2, respectively. If the block is initially
given a velocity of 12 m/s up the ramp, how far from the ramp
will

the block land?

answer is 9.79

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?

A 30 kg block is put on a ramp of angle θ = 30o with
coefficients of static friction 0.3 and kinetic friction 0.2; a
force F1 = 150N is applied to the block to try to stop
it from sliding down, but the force is applied directed at an angle
of θ1 = 60o counterclockwise from the ramp
upward incline

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...

1. A block is resting at the left end of a 12 meter long ramp.
The left end can be raised with a jacking system, while the right
end remains on the level wooden surface. Coefficients of friction
for the ramp are: Static 0.50, Kinetic 0.40. The left end of the
ramp is raised just enough to cause the block to start to
slide.
a) How high was it raised?
b) What is the speed of the block when 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?

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...

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 block of mass m1 begins at the bottom of a ramp that is
inclined an angle θ above the horizontal. It is initially moving up
the ramp with velocity v0. A second block of mass m2 is at rest on
the ramp a distance d up the ramp from the ﬁrst block. Friction
keeps the second block from sliding down. The coeﬃcient of kinetic
friction between the ramp and the blocks is µk for both
blocks.
What is the...

2.A 5 kg wooden block sits on a flat straight-away 12 meters
from the bottom of an infinitely long ramp, which has an angle of
20 degrees. The straightaway has a coefficient of kinetic friction
of 0.4 and the ramp of 0.25. While the block is on the flat
section, you exert a 100 N force at an angle of 45 degrees above
the horizontal, propelling the block towards the ramp.
a.What is the velocity of the block right before...
