A box slides down a ramp with a constant acceleration of 0.300
m/s2. The ramp is raised 18.0o above the
horizontal. Calculate the coefficient of kinetic friction between
the ramp and the box. HINT: Notice that the velocity is not
constant as it was in the previous problem. However, the free body
diagrams for both of these problems are the same. Use the free body
diagram to write out the corresponding Newton's Law equations for
x and y in the case that the acceleration down
the ramp is not zero.
