Determine the change in length of the rope

Reference no: EM13343242

A 54-kg water skier is being pulled by a nylon (Young's modulus 3.7 x 109 N/m2) tow rope that is attached to a boat. The unstretched length of the rope is 11 m and its cross-section area is 2.1 x 10-5 m2. As the skier moves, a resistive force (due to the water) of magnitude 120 N acts on her; this force is directed opposite to her motion. What is the change in length of the rope when the skier has an acceleration whose magnitude is 0.59 m/s2?
