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.

A 17.6-kg crate starts at rest at the top of a 60.0° incline.
The coefficients of friction are μs = 0.400 and
μk = 0.300. The crate is connected to a hanging
8.00-kg box by an ideal rope and pulley.
a) How long does it take the crate to slide 2.00 m down the
incline? ( in seconds)
b)To push the crate back up the incline at constant speed, with
what force should you push on the crate (parallel to...

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.

A crate of fruit with a mass of 39.0 kg and a specific heat
capacity of 3600 J/(kg⋅K) slides 8.70 m down a ramp inclined at an
angle of 38.3 degrees below the horizontal.
Part A If the crate was at rest at the top of the incline and
has a speed of 2.65 m/s at the bottom, how much work Wf was done on
the crate by friction? Use 9.81 m/s2 for the acceleration due to
gravity and express...

A crate of fruit with a mass of 31.0 kg and a specific heat
capacity of 3600 J/(kg?K) slides 7.60 m down a ramp inclined at an
angle of 36.8 degrees below the horizontal.
If the crate was at rest at the top of the incline and has a
speed of 2.05 m/s at the bottom, how much work Wf was done
on the crate by friction?
Use 9.81 m/s2 for the acceleration due to gravity and express

A crate of fruit with a mass of 33.5 kg and a specific heat
capacity of 3800 J/(kg?K) slides 8.30 m down a ramp inclined at an
angle of 37.4 degrees below the horizontal.
If the crate was at rest at the top of the incline and has a
speed of 2.20 m/s at the bottom, how much work Wf was done
on the crate by friction?
Use 9.81 m/s2 for the acceleration due to gravity and express
your answer...

A child leaves her book bag on a slide. The bag, which is at the
top of the slide, starts from rest and reaches the bottom in 1.75
s. The mass of the book bag is 3.20 kg, the length of the slide is
3.30 m and the angle of incline is 28.0°. (Assume the +x-axis to be
parallel to and down the slide. For all values, enter the magnitude
only.)
(a) With what acceleration does the bag go down...

A crate of fruit with a mass of 35.0 kg and a specific heat
capacity of 3800 J/(kg⋅K) slides 8.40 m down a ramp inclined at an
angle of 36.1 degrees below the horizontal.
Part A: If the crate was at rest at the top of the incline and
has a speed of 2.65 m/s at the bottom, how much work Wf was done on
the crate by friction? Use 9.81 m/s2 for the acceleration due to
gravity and express...
