AI Thread Summary
The vector components are given as Ax = +3.9 and Ay = -4, leading to a calculation for the angle from the x-axis. The initial attempt involved using the inverse tangent function, resulting in an angle of -44.27 degrees. To adjust this angle to the correct quadrant, the user added 180 degrees, arriving at 135.7 degrees, which corresponds to option A. However, the correct answer is stated to be 314 degrees, indicating a misunderstanding of the quadrant placement. The discussion emphasizes the importance of correctly identifying the quadrant for vector angles.

Homework Statement



The components of vector are given as follows
Ax= +3.9
Ay= -4

The angle measured counterclockwise from the x-axis to vector , in degrees, is closest to:

A,136





B.134





C.224





D.314





E.46


Homework Equations





The Attempt at a Solution



When I saw this problem I though all we had to do was get the inverse tan of -3.9/4

Which gave me -44.27. I added 180 to place it in the proper quadrent to get 135.7 which is choice A however the answer is 314 which makes no sense

What quadrant do you think it should be in?
 
fourth which is why you would add 360 and not 180.. Thank you!
 

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'

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...
