h) Suppose the block is placed on an inclined plane of angle 0 as shown in the figure. Draw a free-body diagram for the block assuming it is sliding down the incline at constant speed. Mor i) Establish a coordinate system with axes perpendicular and parallel to the incline. Resolve each force into components and write down two relationships that express the fact that the block is moving down the incline with constant speed. j) Solve the equations of part (i) and determine a relationship between the coefficient of friction u and the angle of the incline. Does your result depend on the block's mass or gravity? If not can you explain why?
