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 x- and y-components of each vector, we can use trigonometry. Let's break down each vector into its components:
Vector A⃗:
- Given: Vector A is directed along the negative y-axis and has a length of 8.00 meters.
- Components:
- (since it lies along the y-axis, there's no x-component)
- (since it points in the negative y direction)
Vector B⃗:
- Given: Vector B is located in the first quadrant, makes an angle of 30.0 degrees with the positive y-axis, and has a length of 15.0 meters.
- Components:
- The angle with the positive x-axis:
Vector C⃗:
- Given: Vector C is located in the third quadrant, makes an angle of 25.0 degrees with the negative x-axis, and has a length of 12.0 meters.
- Components:
- The angle with the negative x-axis is .
- The angle with the positive x-axis:
Vector D⃗:
- Given: Vector D is located in the second quadrant, makes an angle of 53.0 degrees with the negative x-axis, and has a length of 10.0 meters.
- Components:
- The angle with the positive x-axis:
Now, let's compute the components:
