### Problem 1/3: Vector Magnitude and Angle Calculation

**Problem Statement:**

For the given vectors **V₁** and **V₂** from Problem 1/2, determine the magnitude of the vector difference **V'** = **V₂** - **V₁** and the angle θₓ which **V'** makes with the positive x-axis. Complete both graphical and algebraic solutions.

**Solution Steps:**

1. **Graphical Solution:**
    - Plot vectors **V₁** and **V₂** on a coordinate system.
    - Draw the vector **V'** from the tip of **V₁** to the tip of **V₂**.
    - Measure the length of **V'** to determine its magnitude.
    - Measure the angle between **V'** and the positive x-axis to find θₓ.
    
2. **Algebraic Solution:**
    - Use the components of **V₁** and **V₂** to calculate the components of **V'**.
    - Compute the magnitude of **V'** using the Pythagorean theorem: 
      \[
      |\mathbf{V'}| = \sqrt{(V'ₓ)^2 + (V'ᵧ)^2}
      \]
    - Calculate the angle θₓ using the arctangent function:
      \[
      θₓ = \tan^{-1} \left(\frac{V'ᵧ}{V'ₓ}\right)
      \]

Note: Ensure you have the information for vectors **V₁** and **V₂** from Problem 1/2 to proceed with the calculations.
