A box of textbooks of mass 25.9kg rests on a loading ramp that makes an angle \alpha with the horizontal. The coefficient of kinetic friction is 0.230 and the coefficient of static friction is 0.360.

1 As the angle \alpha is increased, find the minimum angle at which the box starts to slip.

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

3 At this angle, how fast will the box be moving after it has slid a distance 5.30m along the loading ramp?
