Understanding and Calculating Resultant Vectors: A Comprehensive Guide for SEO
When dealing with vectors, especially in SEO analytics and digital navigation, understanding how to calculate and visualize resultant vectors is crucial. A resultant vector represents the total displacement from the starting point to the final point after moving along multiple vectors. In this guide, we will break down a specific problem and demonstrate the step-by-step process to find the resultant vector. This process involves vector component analysis and the application of basic trigonometric principles, which are essential skills in SEO and other fields requiring spatial and quantitative analysis.
Problem Description
The problem at hand involves a person's movements in different directions:
Walking 100 meters east Walking 300 meters south Walking 150 meters at 30 degrees south of west Walking 200 meters at 60 degrees north of westThe goal is to find the resultant vector's magnitude and direction. This involves breaking down each movement into its x (east-west) and y (north-south) components, summing these components, and then finding the resultant vector's magnitude and direction.
Step-by-Step Solution
Step 1: Break Down Each Movement into Components
100 m Eastx_1 100 m, y_1 0 m300 m Southx_2 0 m, y_2 -300 m150 m at 30 degrees south of westx_3 -150 cos(30°) -150 * (sqrt(3)/2) ≈ -129.9 m, y_3 -150 sin(30°) -150 * (1/2) -75 m200 m at 60 degrees north of westx_4 -200 cos(60°) -200 * (1/2) -100 m, y_4 200 sin(60°) 200 * (sqrt(3)/2) ≈ 173.2 m
Step 2: Sum the Components
Total x-component:x_total x_1 x_2 x_3 x_4 100 0 - 129.9 - 100 -129.9 mTotal y-component:y_total y_1 y_2 y_3 y_4 0 - 300 - 75 173.2 -201.8 m
Step 3: Calculate the Magnitude of the Resultant Vector
To find the magnitude of the resultant vector R:
mag_R sqrt(x_total^2 y_total^2) sqrt((-129.9)^2 (-201.8)^2) ≈ sqrt(16880.01 40696.72) ≈ sqrt(57576.73) ≈ 239.9 m
Step 4: Calculate the Direction of the Resultant Vector
To find the direction angle θ relative to the negative x-axis (West):
theta tan^(-1)(y_total / x_total) tan^(-1)(-201.8 / -129.9) ≈ tan^(-1)(1.55) ≈ 57.7°Since both components are negative, the direction is in the third quadrant. Therefore, the angle relative to the West axis is:- 180° 57.7° -122.3° or 237.7° (measured counterclockwise from East)
Final Result
Magnitude: ≈ 239.9 m
Direction: ≈ 237.7° (237.7° measured counterclockwise from East)
