Math Problem Statement
Solution
To solve this problem, let's break down the information from the image:
Given:
- A vector is shown at an angle of above the positive x-axis.
- The magnitude of the vector is 2 units.
Goal:
We need to express the vector in its component form, based on its magnitude and direction.
Approach:
A vector can be expressed in component form as: where is the horizontal (x-axis) component and is the vertical (y-axis) component.
The horizontal and vertical components are calculated as:
Here, the magnitude and the angle .
Thus:
Solution:
So the vector in component form is:
Correct Answer:
The correct option is D: .
