0. Suppose the ski patrol lowers a rescue sled and victim, having a total mass of 90.0 kg, down a 60.0° lope at constant speed, as shown below. 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? (b) How much work is done by he rope on the sled in this distance? (c) What is the work done by the gravitational force on the sled? (d) What s the total work done? 60° 13 W f

University Physics 1 - Work and Kinetic Energy
I need help with this problem and a very detailed explanation of the solutions described below:
Transcribed Image Text:30. Suppose the ski patrol lowers a rescue sled and victim, having a total mass of 90.0 kg, down a 60.0°
slope at constant speed, as shown below. 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? (b) How much work is done by
the rope on the sled in this distance? (c) What is the work done by the gravitational force on the sled? (d) What
is the total work done?
