FIGURE 8-10 An object of mass m is at rest on a rough inclined plane with height h, length 8 m, and which makes an angle of 30° with the horizontal. The object is allowed to move and it stops on a rough horizontal surface, at a distance of 4 m from the bottom of the inclined plane, as shown in Figure 8-10. The coefficient of kinetic friction on the inclined plane is 0.4 and g = 10 m/s 2 .
