14. Mount Kilimanjaro in Tanzania is the highest mountain in Africa reaching a height of 4.9 kmfrom its base to the peak. A mountain climber with all her gear has a mass of 85 kg. In exactly 1.5 hours she climbs from the base to an elevation of 2700 m, takes a break and then it takes her another hour to climb to an elevation of 3800 m. A storm hits and she must camp for the night at this elevation. (Elevation means relative to the ground.) a. At the location of the first break, how much gravitational potential energy does she have at this elevation? [1-2] b. At the camp site, how much gravitational potential energy does she have, relative to the location of her first break? [1-3] I c. Calculate the power of the climber during the 1" part of the trip and then calculate the power of the climber during the 2"d part of the trip. In which part of the climb was she more powerful? [A-5)
