# Quick and simple Power problem

• opqpop
In summary, the task was to find the minimum power output used by a 68.8kg athlete to climb a vertical distance of 4.74m in 8.70s during a rope climb. The formula used was P = mgh/t, resulting in an answer of 367 W. However, this was considered incorrect and it was suggested to use g=9.81 to round the answer to 368 W. The question of whether this is the correct approach was also raised.

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?

If you use g=9.81 the answer should round to 368 W

But is this the right way to do this problem?

Yes. It's probably a rounding problem as kamerling pointed out.
