Jenny (mass = 63 kg) is skiing down a 17° slope. A tailwind is assisting her as she travels down the slow with a force of 18 N (parallel to the slope). The coefficient of dynamic friction between Jenny’s skis and the snow is 0.04. Assuming the ski hill is perfectly smooth and the net force in the vertical (y) direction is zero, what is the resultant (net) external force acting on Jenny and what is her acceleration? Include a free body diagram to illustrate the scenario, show complete workings, and report answers to two (2) decimals (with units and direction as required).
