Suppose the ski patrol lowers a rescue sled and victim, having a total mass of 80.0 kg down a 60° slope at constant speed, as shown in the figure. The coefficient of friction between the sled and the snow is 0.100. (a) How much work is done by friction as the sled moves 30.0 m along the hill. Enter to 3 significant figures Wfric -39.2 J (b) How much work is done by the rope on the sled in this distance? Hint: use Newton's second law to find the tension.
