Have you not learned trigonometry yet? What do you not understand here? Explain what is giving you trouble!
 
  • #3
SOHCAHTOA would be useful to use in this problem.
 
  • #4
All of your posts have to do with the same basic thing, vector addition. Did you take any notes on this or do you have a textbook that you use in the class where you could review the concepts?

Man oh man, every single one of your posts shows no relevant equations and no attempt at a solution. How black is your soul, really?

This is a forum for physics *help*. Not cheating. There are other websites for that. Actually, there are advertisements for such websites on this forum so...
 

1. What are component vectors?

Component vectors are used in mathematics and physics to break down a vector into its horizontal and vertical components. This allows for easier analysis and calculation of vector quantities.

2. How do you find the angle of a component vector with a magnitude of 25 and an x component of 12?

To find the angle of a component vector with a magnitude of 25 and an x component of 12, you can use the inverse tangent function (tan^-1) to find the ratio of the vertical component to the horizontal component. This will give you the angle in radians, which can be converted to degrees if needed.

3. Why is knowing the angle of a component vector important?

Knowing the angle of a component vector is important because it allows you to determine the direction of the vector. It also helps in vector addition and subtraction, as the angles of the components must be considered in order to accurately calculate the resultant vector.

4. Can the magnitude and components of a vector be negative?

Yes, the magnitude and components of a vector can be negative. This indicates the direction in which the vector is pointing. A negative magnitude means the vector is pointing in the opposite direction, while negative components indicate the vector is pointing in the opposite direction of that particular axis.

5. How can component vectors be used in real-world applications?

Component vectors have various real-world applications, such as in navigation and engineering. They are used to calculate forces, velocities, and displacements in a specific direction. They are also used in computer graphics to determine the direction and movement of objects.
