A 2.0 kg box rests on a plank that is inclined at an angle of 65degree above the horizontal. The upper end of the box is attachedto a spring with a force constant of 310 N/m. If the coefficient ofstatic friction between the box and the plank is 0.27, what is themaximum amount the spring can be stretched and the box remain atrest?
Xmax=____cm
