Question

A 30-kg crate starts from rest, slides down a frictionless incline and then along a rough horizontal surface until it comes to rest. The coefficient of kinetic friction between the horizontal surface and the crate is 0.27. If the crate’s initial height is 9 m, find the distance it travels on the horizontal surface.

Answer #1

A crate is placed on an incline. The 30 kg crate starts at rest
and then slides 1.5 m along a 35˝ incline. The coefficient of
kinetic friction between the crate and the incline is uk= 0.50. X
is down the incline and Y is perpendicular to the incline.
Determine the net force acting on the crate, including (Fg, Fn, and
Fk). And what is the final speed of the box.

An object of mass m1=0.410kg starts from rest at point A and
slides down an incline surface that makes an angle of 25.0° with
the horizontal. The coefficient of kinetic friction between the

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...

A 5.0 kg box slides down a 5.0 m high frictionless hill,
starting from rest, across a 2.0 m wide horizontal surface, then
hits a horizontal spring with spring constant 500 N/m. The ground
