A firefighter wishes to aim his fire hose such that the stream of water
goes directly into the second story which has caught on fire. The second
story window is at a he
Problem 1. A skier of mass m is being pulled horizontally by a rope at a constant
speed of v. The coefficient of kinetic friction between the skis and the snow is k.
Determine the tension in the rope. Check the answer for dimensional consistency.
