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 xx- and yy-components of the vectors A\mathbf{A}, B\mathbf{B}, C\mathbf{C}, and D\mathbf{D}, we'll use trigonometry. Each vector can be decomposed into its components using the following formulas:

  • xx-component: Magnitude×cos(Angle)\text{Magnitude} \times \cos(\text{Angle})
  • yy-component: Magnitude×sin(Angle)\text{Magnitude} \times \sin(\text{Angle})

Let's go through each vector one by one.

1. Vector A\mathbf{A}

  • Direction: Along the negative yy-axis.
  • Magnitude: 8.00 meters.

Since A\mathbf{A} is directed entirely along the negative yy-axis:

  • Ax=0A_x = 0 meters
  • Ay=8.00A_y = -8.00 meters

2. Vector B\mathbf{B}

  • Direction: Located in
