Magnitude and direction of the resultant.

AI Thread Summary
To find the magnitude of the resultant vector from two arrows, one going down 13m and the other up 3m, you subtract the upward vector from the downward vector, resulting in -10m. The magnitude is the absolute value of this result, which is 10m. The direction of the resultant vector is south, as it is the larger downward vector. Clarification is needed on whether the vectors are labeled as "up" and "down" or "north" and "south." Understanding the correct terminology is essential for accurate interpretation of the problem.

Question:

i have 2 arrows/vector. One going down 13m and one going up 3m. it ask what is the magnitude and direction.

Direction should be south and north. But how do i find the magnitude? and what is that?

is it:

-13 + 3 = -10m?

That's pretty much correct, but the magnitude would be the absolute value of what you wrote.

Does the problem say the vectors are "up" and "down", or does it say "north" and "south"? The direction will be one of those.
 

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...
