Question

To test a slide at an amusement park, a block of wood with mass 3.00 kg is released at the top of the slide and slides down to the horizontal section at the end, a vertical distance of 23.0 mm below the starting point. The block flies off the ramp in a horizontal direction and then lands on the ground after traveling through the air 30.0 mm horizontally and 40.0 mm downward. Neglect air resistance.

How much work does friction do on the block as it slides down the ramp?

Answer #1

A wood block of Mass M=3.00 kg and rests horizontally at the
bottom of a ramp. A bullet of mass m=0.0420kg with an intial
velocity v0 is fired at the wood block and embedded inside the
block. The wood blocl and the embedded bullet together move up the
ramp and reach a vertical heigh of yf= 2.40m relative to the bottom
of the rmap(yo=0) before sliding downward. Ignore friction/air
resistance.

A horizontal force of 60.0 N is applied to a 3.00 kg block as
the block slides a distance of 0.500 m up a ramp. The ramp is
inclined at an angle of 30.0◦ and the coefficient of kinetic
friction between the ramp and the block is 0.600. If the block is
initially at rest, how fast is it moving at the end of the
displacement? Please make answer very detailed

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

A 1.55-kg block is launched by a spring and slides along a ramp
as shown. The spring has a spring constant of 1180 N/m and is
compressed a distance, x, before being released. The block slides
up a frictionless ramp of height, H=0.550 m, above where the block
leaves the spring. At the top of the ramp it flies horizontally off
the ramp. Just before leaving the ramp, the kinetic energy of the
block is 8.54 J. After leaving the...

A 4.25 kg block is projected at 5.40 m/s up a plane that is
inclined at 30.0° with the horizontal. The block slides some
distance up the incline, stops turns around and slides back down to
the bottom. When it reaches the bottom of the incline again, it is
traveling with a speed of 3.80 m/s. If the coefficient of kinetic
friction between the block and the plane is 0.500, how far up the
incline did the block slide?

A block with a mass of 12.0 kg is initially at rest at the top
of a plane that is inclined at an angle of 30.0° above the
horizontal. The block slides down the plane and is traveling with a
speed of 1.50 m/s when it reaches the bottom. If the plane is 0.750
m long, what is the coefficient of kinetic friction between the
block and the plane? please explain each step.

A 2.0 kg wood block is launched up a wooden ramp that is
inclined at a 35 ∘ angle. The block’s initial speed is 10 m/s . The
coefficient of kinetic friction between the block and the ramp is
μk = 0.20.

point?

A block of mass m is initially held at rest at point P on an
incline that makes an angle q with respect to horizontal. The
coefficient of kinetic friction between the block and the incline
is mk. After the block slides down the incline from point P, it
starts to slide without friction up a vertical circular track of
radius R. When it reaches the top of the circle, the normal force
(downward) by the track to the block...

It is generally a good idea to gain an understanding of the
"size" of units. Consider the objects and calculate the kinetic
energy of each one.
