A 73-kg snow skier is being pulled up a 19° slope by a steel (Young's modulus 2.0 x 10¹1 N/m²) cable. The cable has a cross-section area of 8.2 x 105 m². The cable applies a force to the skier, and, in doing so, the cable stretches by 2.6 x 104 m. A frictional force of magnitude 88 N acts on the skis and is directed opposite to the skier's motion. If the skier's acceleration up the slope has a magnitude of 1.4 m/s², what is the original (unstretched) length of the cable? Number Units

A 73-kg snow skier is being pulled up a 19° slope by a steel (Young's modulus 2.0 x 1011 N/m²) cable. The cable has a cross-section area
of 8.2 x 105 m². The cable applies a force to the skier, and, in doing so, the cable stretches by 2.6 x 104 m. A frictional force of
magnitude 88 N acts on the skis and is directed opposite to the skier's motion. If the skier's acceleration up the slope has a magnitude
of 1.4 m/s², what is the original (unstretched) length of the cable?
