1. In the rope climb, a 68.8kg athlete climbs a vertical distance of 4.74m in 8.70s. What minimum power output was used to accomplish this feat? 2. Average Power = Work / time 3. P = mgh/t = 367 W, which is apparently the wrong answer (this is an online course where you input the answer and they tell you if it's correct). I also tried -367W but that doesn't work either. Perhaps this has something to do with the problem asking for minimum power output? Could someone help me out?
