From the top of the wedge, whose length l = 2 m and height h = 1 m, a small body begins to slide. The coefficient of friction between the body and the wedge is f = 0.15. Determine: 1) the acceleration with which the body moves, 2) the time it takes for the body to pass along the wedge; 3) body speed at the base of the wedge.
