Suppose the ski patrol raises a rescue sled and victim, having a total mass of 85.0 kg, up a ? = 62.0° slope at constant speed, as shown in the figure. DO NOT USE THE ANGLE SHOWN IN THE FIGURE! USE THE ANGLE IN THE PROBLEM STATEMENT ABOVE. The coefficient of friction between the sled and the snow is 0.130. Calculate the normal force on the sled (in N). Calculate the work done (in J) by the force of friction as the sled moves 30.0 m up the hill. (Hint: Think about the direction of the friction force. Should it be different than the direction shown in the figure?). Calculate the work done (in J) by the tension force in the rope on the sled over this distance. Calculate the work done (in J) done by the force of gravity on the sled over this distance.

You may have noticed runaway truck lanes while driving in the mountains. These gravel-filled lanes are designed to stop trucks that have lost their brakes on mountain grades. Typically, such a lane is horizontal (if possible) and about 35.0 m long. Think of the ground as exerting a frictional drag force on the truck. A truck enters a typical runaway lane with a speed of 55.5 mph (24.8 m/s). Use the work-energy theorem to find the minimum coefficient of kinetic friction between the truck and the lane to be able to stop the truck.
