A 25-kg box of textbooks rests on a loading ramp that makes an angle of Θ with the horizontal. The coefficient of kinetic friction is 0.25, and the coefficient of static friction is 0.35. (a) Find the minimum angle at which the box is about to move if the angle of the ramp increases gradually. (b) At this angle, find the acceleration of the box. (c) At this angle, how fast will the box be moving after it has slid 5-m along the loading ramp? Specify the given completely, required (what is being asked), complete solution and the final answer for each question.
