Which better predicts Horsepower- weight or speed

AI Thread Summary
The discussion centers on determining whether weight or speed is a better predictor of horsepower in the context of vertical motion. It highlights that both weight (force due to gravity) and speed (velocity) are direct factors influencing horsepower, as expressed in the equation P = Fv. The conversation suggests that since both elements are necessary for calculating horsepower, they may be equally important. The importance of using the correct units, such as converting watts to horsepower, is also mentioned. Ultimately, the relationship between weight and speed in predicting horsepower is complex and requires considering both factors together.

Which better "predicts" Horsepower- weight or speed

1. This problem involves vertical motion on a flight of stairs, the force of friction is to be ignored. I just can quite put my thumb on whether speed or weight will better predict the resulting horsepower, given that weight (mass times gravitational field strength) times velocity (meters per second) is equivalent to horsepower. Can someone help me please?



2. Weight being (N) and speed being (m/s)


3. As I explained I cannot find which one would better "predict" HP, since both are direct factors. Perhaps would that make them equal?

P = Fv, so you need BOTH the force (weight) and the velocity.
Note that this will come out in units of watts if you use the metric system. You'll have to look up the conversion to horsepower.
 
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...
