Math Problem Statement

let Vector A= 293 units @ 61.8 degrees Vector B=189 units @ 260.4 degrees Vector C= 309 units @ 188.7 degrees Vector A + Vector B

Solution

To find the sum of Vector A and Vector B, we need to break them into their component forms (x and y components) and then add these components together.

Step 1: Break vectors into components

  1. Vector A:

    • Magnitude = 293 units
    • Angle = 61.8 degrees
    • Ax=293cos(61.8)A_x = 293 \cos(61.8^\circ)
    • Ay=293sin(61.8)A_y = 293 \sin(61.8^\circ)
  2. Vector B:

    • Magnitude = 189 units
    • Angle = 260.4 degrees
    • Bx=189cos(260.4)B_x = 189 \cos(260.4^\circ)
    • By=189sin(260.4)B_y = 189 \sin(260.4^\circ)

Step 2: Calculate components

Let's compute these components.The components of the vectors are:

  • Vector A:
    Ax138.46A_x \approx 138.46 units
    Ay258.22A_y \approx 258.22 units

  • Vector B:
    Bx31.52B_x \approx -31.52 units
    By186.35B_y \approx -186.35 units

Step 3: Sum of Vector A and Vector B

  • (Ax+Bx)106.94(A_x + B_x) \approx 106.94 units
  • (Ay+By)71.87(A_y + B_y) \approx 71.87 units

Resultant Vector

The resultant vector R=A+B\vec{R} = \vec{A} + \vec{B} in component form is approximately: R(106.94i^+71.87j^) units\vec{R} \approx (106.94 \hat{i} + 71.87 \hat{j}) \text{ units}

Do you want to find the magnitude and direction of the resultant vector or have any other questions?
