b. when the coefficient of kinetic friction is 0.200.

Answer #1

A
7.00-kg box sits on a ramp that is inclined at 36.3 ∘ above the
horizontal. The coefficient of kinetic friction between the box and
the ramp is 0.31.

incline with a constant acceleration of
4.30 m/s2 ?

A horizontal force of magnitude F = 100 N is applied to slide a
block of mass m = 5 kg up a ramp inclined at θ = 37 o to the
horizontal. If the coefficient of kinetic friction between the
block and the ramp is 0.4, what will be the acceleration of the
block?

A 10.0-kg microwave oven is pushed 7.00 m up the sloping surface
of a loading ramp inclined at an angle of 36.9 ? above the
horizontal, by a constant force F with a magnitude 109 N and acting
parallel to the ramp. The coefficient of kinetic friction between
the oven and the ramp is 0.259.

14. Bob drags a box with a mass m=45kg up a ramp. The ramp makes
an angle of 25◦ with the horizontal direction. Bob pulls the the
box upwards at a constant velocity 5m/s by applying a force F~
whose direction makes angle of 30◦ with the ramp. The coefficient
of kinetic friction between the ramp and the box µk = 0.2.
Determine the magnitude of the force F~ .
Answer is F=275.7N

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

There is a 690 kg box being pushed up an inclined surface by a
horizontal force of 5500 N. As it is being pushed, its speed goes
from 1.5 m/s to 2.6 m/s. How much energy is transformed into
thermal energy as it is pushed 3.0 meters up the incline? The angle
of inclination is 30 degrees.

A woman attempts to push a box of books that has mass m
up a ramp inclined at an angle α above the horizontal. The
coefficients of friction between the ramp and the box are
μs and μk. The force
F⃗ applied by the woman is
horizontal.
Assume that μs is less than this critical value. What
magnitude of force must the woman apply to keep the box moving up
the ramp at constant speed?

4) A 5.0 kg box slides 2.00 m down a ramp that is inclined at
300 below the horizontal. The coefficient of kinetic friction
between the box and the ramp’s surface is 0.20
