Solve the all parts of given question:
Question: A box of textbooks of mass 25.8kg rests on a loading ramp that makes an angle alpha with the horizontal. The coefficient of kinetic friction is 0.25 and the coefficient of static friction is 0.36.
Part A: At this angle, find the acceleration once the box has begun to move.
Part B: At this angle, how fast will the box be moving after it has slid a distance 5.4m along the loading ramp?
Please include formulas and show work and steps to find the acceleration once the box has begun to move.
