Math Problem Statement
Four vectors start at the origin of the x y axes labeled O. Vector A is directed along the negative y axis and has a length of 8.00 meters. Vector B is located in the first quadrant, it makes an angle of 30.0 degrees with the positive y axis and has a length of 15.0 meters. Vector C is located in the third quadrant, it makes an angle of 25.0 degrees with the negative x axis and has a length of 12.0 meters. Vector D is located in the second quadrant, it makes an angle of 53.0 degrees with the negative x axis and has a length of 10.0 meters. - Four vectors starting at the origin
Compute the x- and y-components of the vectors A⃗, B⃗, C⃗, and D⃗ in (Figure 1).
Express your answer in meters.
Solution
To find the - and -components of the vectors , , , and , we'll use trigonometry. Each vector can be decomposed into its components using the following formulas:
- -component:
- -component:
Let's go through each vector one by one.
1. Vector
- Direction: Along the negative -axis.
- Magnitude: 8.00 meters.
Since is directed entirely along the negative -axis:
- meters
- meters
2. Vector
- Direction: Located in
