Question

A 3.00-kg block is sent up a ramp of angle θ equal to 43.0° with an initial velocity ν0 equal to 23.0 m/s. Between the block and the ramp, the coeffiient of kinetic friction is μk equal to 0.50 and the coefficient of static friction is μs equal to 0.80. 1) How far up the ramp (in the direction along the ramp) does the block go before it comes to a stop? (Express your answer to two significant figures.)

Answer #1

Work done by friction and gravity is equal to change in kinetic
energy. Final kinetic energy is zero. We use this to find the
required distance as shown below***************************************************************************************************

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?

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 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) On the drawing draw the forces and their components
b) Derive the formula for the Normal force and...

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

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 with mass m1 = 8.8 kg is on an incline with
an angle θ = 40° with respect to the horizontal. For the first
question there is no friction, but for the rest of this problem the
coefficients of friction are: μk = 0.38 and
μs = 0.418.
1. When there is no friction, what is the magnitude of the
acceleration of the block?
2. Now with friction, what is the magnitude of the acceleration
of the block...

A block of mass 19.6 kg starts at rest at the top of a
frictionless ramp that makes an angle of 36.2 ^\circ ∘ below the
horizontal. After it slides without friction down the entire 2.89 m
length of the ramp, it begins to slide horizontally along a rough
concrete surface with a coefficient of kinetic friction of
\mu_kμ k = 0.503 until it slows to a complete
stop. How far does the block slide horizontally along the concrete
before...
