Consult Multiple-Concept Example 13 to review a model for solving this type of problem. A 61-kg snow skier is being pulled up a 12 slope by a steel cable. The cable has a cross-sectional area of 7.8 105 m2 . The cable applies a force to the skier, and, in doing so, the cable stretches by 2.0 104 m. A frictional force of magnitude 68 N acts on the skis and is directed opposite to the skiers motion. If the skiers acceleration up the slope has a magnitude of 1.1 m/s2 , what is the original (unstretched) length of the cable?
