**Physics Problem: Skier on a Slope** **Scenario:** Suppose the ski patrol lowers a victim of a ski accident down a slope with an angle \( \theta = 42^\circ \), using a rope going parallel up the slope. The victim and sled have a total mass of 95 kg. The coefficient of friction between the sled and the snow is 0.095. **Tasks:** (a) **Free-Body Diagram:** Draw a thorough free-body diagram for the sled-plus-person system. *Hint:* Consider the gravitational force, normal force, frictional force, and tension from the rope in your diagram. **Calculations:** Calculate the work done by each of the forces as the person is lowered along the slope by 50 m: (b) **Frictional Force:** Determine the work done by friction. (c) **Tension in the Rope:** Calculate the work done by the rope. (d) **Gravitational Force:** Find the work done by the gravitational force. (e) **Normal Force:** Evaluate the work done by the normal force. (f) **Total Work:** Compute the total work done on the person/sled by all the forces. **Explanation of the Diagram:** The diagram accompanying this problem depicts a snow-covered slope with a sled being lowered by a rope. The angle \( \theta \) represents the inclination of the slope with horizontal. This angle is crucial in resolving forces into components parallel and perpendicular to the slope.
