AI Thread Summary
To calculate the minimum power output for a 68.8kg athlete climbing 4.74m in 8.70s, the formula used is P = mgh/t, which results in an output of approximately 367 W. However, this answer was deemed incorrect in an online course setting. A suggestion was made to use g=9.81 for gravity, which rounds the answer to 368 W. The discussion highlights that the discrepancy may stem from rounding issues. Clarification on the correct approach to the problem was sought, confirming that the method used is appropriate.

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.
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
