An 80.6 kilogram climber is scaling the vertical wall of a mountain. His safety rope is made of nylon that, when stretched, behaves like a spring with a spring constant of 1.24 x 103 N/m. He accidentally slips and falls freely for 0.731 meter before the rope runs out of slack.
Evaluate how much is the rope stretched when it breaks his fall and momentarily brings him to rest?
