A recreational motor boat on a lake is towing a 70-kg water skier. She holds on to a nylon tow rope of length 12 m with a cross sectional area of 2.0 10-5 m2. As the boat and she starts moving, she is subjected to a horizontal drag force of 125 N from the water. If she moves with an acceleration of 0.85 m/s2, by how much does the rope stretch? Young's modulus for nylon is 3.7 109 N/m2.
