Find Parallel Component of Vector B to Vector A | Basic Unit Vector Help

AI Thread Summary
To find the parallel component of vector B to vector A, which is represented as A = 3i + 4j, one must first understand the relationship between the vectors' components. Vector B has components of 2 and 6, indicating its position in the Cartesian plane. The discussion highlights confusion around calculating the parallel vector and the application of the equation S(A) = B. Participants suggest reviewing textbook materials for clarity on vector components and the concept of parallelism. A simple equation or example is requested to aid understanding of how to derive the parallel component effectively.

Homework Statement



Vector B has x- and y-components 2 and 6, respectively. Compute the component of B that is parallel to A.

A is 3i+4j

Homework Equations



The basic S(A)=B is all I know.

The Attempt at a Solution



No clue. Was absent yesterday. (Which is why I need help, lol.)

what do you know about i-hat and j-hat .let me give you example from your question A is 3i + 4j .so which means 3 unit to the right and 4 unit up which actualy mean X- and Y- components .so according to this figure out what is 2 and 6 ...Read your textbook for more information
 
I don't think you understood the question I asked. I know that the axis are represented as I J & K, and that the equation is basically the coordinates for a point. I can find the magnitude, angle, and components to a basic vector or a resultant; I don't understand how to calculate a parallel vector between an existing vector and a component of a second.

Edit: A simple equation or example would help greatly, I just don't understand how you could apply S(A)=B to binomials that aren't multiples.

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...
