QUESTION 3 14.3 points Save Answer The climber in the previous example problem was moving roguhly 12 m/s when their rope came tight and beghan to catch them, After being caught, their speed was zero and stertch in the rope had allowed them to move downward by an additionla 2.0 m, Assuming the mass of the climber is 75kg, what was their change in kinetic energy while being caught by the rope? oo What was their change in potential ernergy while being caught by the rope? 1470 According to the Law of Conservation of Energy, how much work was done on the person by the rope (neglect the same amount of work done by air resistance)? | -3930 J The dynamic ropes is used in rock climbing are designed to be stretchy, but only slightly elastic so the climber doesn't bounce. Due to strectch in the rope, the work done on the climber occured over a distance of 2.0m. Calculate the average net force applied to the climber. If a static rope was used, so the stretch was only 0.20 m while catching the climver the average net force applied to the climber would be times greater. This type of non-stretchy static rope should rope should not be used for roack climbing Earlier we calculated the work done on the climber by the rope. An equal, but negative work was done on the rope does not go tinto mechnical energy. Therfore, that energy must have been conberted to i} energy in the rope. which means structuaral damage on the microscopic level. Climbing ropes are only rated for a certain number falls to ensure they are replaced before that damage accumulates to the point where the rope ks when catching a gall
