9. A 1.90 kg box rests on a plank that is inclined at an angle
of 29° above the horizontal. The upper end of the box is attached
to a spring with a force constant of 18 N/m, as shown in the
figure. If the coefficient of static friction between the box and
the plank is 0.79, what is the maximum amount the spring can be
compressed and the box remain at rest?
