Question

Suppose the ski patrol lowers a rescue sled and victim,
having a total mass of 90.0 kg, down a 60.0º slope at
constant speed, as shown in Figure 7.36. The coefficient of
friction between the sled and the snow is 0.100. What is the work done by the gravitational force on the sled? What is the total work done?
