How do you the find magnitude and x component of a vector?

AI Thread Summary
To find the x component and magnitude of vector A, it's essential to recognize that the vector -5.2 A has a magnitude of 47 m and points in the positive x direction. The x component can be calculated using the formula Ax = magnitude × cos(θ), where θ is the angle of the vector. Since the vector points along the x-axis, the angle is 0 degrees, making Ax equal to the magnitude of 47 m. The magnitude of vector A remains 47 m, as it is not affected by the negative sign in -5.2 A. Understanding these components is crucial for solving vector problems effectively.

2. Vector A = Ax + Ay
Ax = magnitude X xi
Ay = magnitude X yi

3. I don't know how to start.
 
any way to provide the diagram?

Try starting by figuring out how long A is, and in what direction it points.

Hi egadda2! Welcome to PF! :smile:

(try using the X2 tag just above the Reply box :wink:)

That's very confused :redface:

you mean A = Ax x i + Ay x j.

ok, so in this case Ax = … ? :smile:
 
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...

Figure 1 Overall Structure Diagram Figure 2: Top view of the piston when it is cylindrical A circular opening is created at a height of 5 meters above the water surface. Inside this opening is a sleeve-type piston with a cross-sectional area of 1 square meter. The piston is pulled to the right at a constant speed. The pulling force is(Figure 2): F = ρshg = 1000 × 1 × 5 × 10 = 50,000 N. Figure 3: Modifying the structure to incorporate a fixed internal piston When I modify the piston...
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...
