An 2.00 kg box is initially at rest on a ramp inclined at
23° below the horizontal. The coefficient of static
friction is 0.310 and the coefficient of kinetic friction is
0.220. The box begins to slide down the ramp.
a) Find the acceleration of the box.
b) If it takes the box 3.00 s to slide to the base of the
ramp, over what length of ramp did it slide?
c) What was the initial height of the box above the
ground?
d) What magnitude of force F, applied perpendicularly to
the top of the box (pressing it against the ramp) is needed.
to prevent the box from starting to slide?
