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 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

Thread 'Voltmeter readings for this circuit with switches'

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...
