What is the change in length of the rope

Reference no: EM13334787

A 62-kg water skier is being pulled by a nylon (Young's modulus 3.7 x 109N/m2) tow rope that is attached to a boat. The unstretched length of the rope is 10 m and its cross-section area is 2.2 x 10-5 m2. As the skier moves, a resistive force (due to the water) of magnitude 190 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 0.49 m/s2?
