The vector -5.2 has a magnitude of 32 and points in the positive direction.?

AI Thread Summary
The discussion revolves around understanding the vector notation and its components, specifically the vector -5.2A with a magnitude of 32. Participants express confusion about the meaning of -5.2A and whether it indicates components or a specific vector name. Clarification is sought regarding the angle of the vector with the x-axis, which is essential for determining its components. A participant shares an email from their professor indicating that the x-component Ax can be calculated using the equation Ax = (34m) / (-5.2), resulting in a negative value, which indicates the vector points in the negative x-direction. The magnitude of vector A is determined to be the absolute value of Ax, confirming it has no y-component.

Find the x component of the vector A?

Find the magnitude of the vector A?

Please also explain your work too

thanks in advance

What do you mean by "the vector -5.2"?
 
Hi MrGoodyear812, welcome to the PF.
You have not posted the actual problem. In the title, what is -5.2 and 32?
 
OH! SORRY!

it should be the vectore

-5.2A

If you want the components of a vector, you most know the angle made by the vector with x-axis. What is that angle?

Thats why this problem is killing me...its not enough info

thats honestly everything the book gave us
 
I don't get it, is -5.2A the name of the vector? That doesn't make any sense. Are -5 and 2 the components? Doesn't make sense that they would just ask for the x component. What the heck is the A for?

Maybe if you could write the problem statement word for word it would help.
 
5.2 is the value of hte vector is what I am understanding...idk I am so confused...

and that is word for word
 
Just got this email from my prof

Bx = 34m in this case --> Ax = (34m) / (-5.2) = ?? (a negative number), so vecA is pointing in the negative x-direction. The magnitude of A will just be |Ax| (since there's no y-component), which is positive.
