The inclined plаne in the figure аbоve hаs twо sectiоns of equal length and different roughness. The dashed line shows where section 1 ends and section 2 begins. A block of mass is placed at different locations on the incline. The coefficients of kinetic and static friction between the block and each section are shown in the table below. Coefficient of Friction Section 1 Section 2 Static Kinetic If the block is at rest on section 1 of the incline, what is the magnitude of the force of static friction exerted on the block by the incline?
