Answer #1

A 5.00-kg5.00-kg block is sent up a ramp inclined at an angle
?=28.0∘θ=28.0∘ from the horizontal. It is given an initial velocity
?0=15.0 m/sv0=15.0 m/s up the ramp. Between the block and the ramp,
the coefficient of kinetic friction is ?k=0.50μk=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?

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 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?

A 2 kg block is pushed up a 60 degree inclined with an initial
velocity of 4 m/s on a surface whose coefficient of friction is
0.1. How far does the block travel up the incline when it comes to
a complete stop?

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

An 8.70-kg block slides with an initial speed of 1.80 m/s down a
ramp inclined at an angle of 25.3 ∘ with the horizontal. The
coefficient of kinetic friction between the block and the ramp is
0.87. Use energy conservation to find the distance the block slides
before coming to rest.

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
highest...

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...

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?
