What Are the Components of These Two Vectors?

Click For Summary
SUMMARY

The discussion focuses on calculating the components of two vectors: Vector A, which is 3.28 m long and aligned with the x-axis, and Vector B, which is 190.6 cm long and directed at +25° to the positive x-axis. The components of Vector A are straightforward, with Ax = 3.28 m and Ay = 0 m. For Vector B, the components are determined using trigonometric functions, yielding Bx = 190.6 cm * cos(25°) and By = 190.6 cm * sin(25°). The resultant vector can be calculated by summing the components of both vectors and then determining its magnitude and direction.

PREREQUISITES
  • Understanding of vector components and their representation

Homework Statement



Vector A is 3.28 m long and points along the x axis. Vector B is 190.6 cm long and points at +25° to the positive x axis
(a) What are the components of Vector A?
(b) What are the components of Vector B?
(c) What is the resultant of these two vectors in terms of components?
(d) What is the resultant of these two vectors in terms of magnitude and direction

Homework Equations


I think we are trying to find Ax, Ay, Bx, and By


The Attempt at a Solution


I am not certain on where to begin here, any help would be good, thanks!

Try drawing each vector in its own coordinate axis first with repsect to the origin. The magnitude of vectors will always be the norm or hypentenuse of a right triangle. Since you are given an angle with respect to the horizontal axis and a magnitude, you can use trig to break it apart into its components. Try that and see if you can't make sense of (c) & (d) from that relationship.
