A box of textbooks of mass 27.7 kg rests on a loading ramp that makes an angle. with the horizontal. The coefficient of kinetic friction is 0.25 and the coefficient of static friction is 0.37.

Part A As the angle, is increased, find the minimum angle at which the box starts to slip.

Part B At this angle, find the acceleration once the box has begun to move.

Part C At this angle, how fast will the box be moving after it has slid a distance 5.5 m along the loading ramp?
