2. A box slides from rest from point A down a plane inclined 30-angle to the horizontal. After reaching the bottom of the inclined plane, the box moves on horizontal floor at a distance 2.0 m before coming to rest. If the coefficient of friction between the box and the plane and between the box and the floor is 0.40. What is the distance of point A from the intersection of plane and the floor? 4x Mz0.4 Lb d= 2.0m.
