'horizontal force F causes block - of mass slide up rough incline surface with an acceleration of magnitude The surface inclined at an angle above the horizontal: Orient the positive X-axis Up the ramp What does the term "rough surface" mean? What type of friction (kinetic or static) acts on the block? What is the direction of the frictional force acting on the block? Draw - free body diagram for the block: Determine an expression for the magnitude of the frictional force acting on the block in terms of the quantities given in the problem (m; and/or a) and perhaps _ constants (eg: 1,%,9, Determine expression for the magnitude of the normal force acting on the block in terms of the quantities given in the problem (m, F 0 and/or a) and, perhaps, constants (e.&+, Tt, %i, g,= If F = 200 N, m 15, cm/s' , and 20.0", calculate numerical values for the magnitudes of the normal and frictional forces. (207 N, 134 N} What the coefficient of friction between the block and: the Incline surface? (0.648}'
