Suppose the ski patrol lowers a rescue sled and victim, having a total mass of 90.8 kg, down a 54.9° slope at constant speed, as shown in the figure. The coefficient of friction between the sled and the snow is 0.100. W T (a) How much work is done (in J) by friction as the sled moves 30 m along the hill? (b) How much work is done (in J) by the rope on the sled in this distance? (c) What is the work done (in J) by gravity on the sled? (d) What is the total work done (in J)?
