At the end of the walk, the person's resultant displacement is 495.1 m at 63⁰ south of west.
<h3>What is resultant displacement?</h3>
The resultant displacement of an object is the change in position of the object. It can be described as the shortest distance connecting the final position of the object to the initial position of the object.
<h3>Net horizontal displacement </h3>
Path 1 = 40 m
Path 2 = 0 m
Path 3 = 110 m x cos(30) = 95.26 m
Path 4 = 180 m x cos(60) = 90 m
Total horizontal displacement, X = 40 m + 0 m + 95.26 m + 90 m = 225.26 m
<h3>Net vertical displacement </h3>
Path 1 = 0 m
Path 2 = 230 m
Path 3 = 110 m x sin(30) = 55 m
Path 4 = 180 m x sin(60) = 155.885 m
Total horizontal displacement, Y = 0 m + 230 m + 55 m + 155.885 m = 440.885 m
<h3>Resultant displacement</h3>
R = √(X² + Y²)
R = √(225.26² + 440.885²)
R = 495.1 m
<h3>Direction of the displacement</h3>
θ = arc tan (Y/X)
θ = arc tan (440.885/225.26)
θ = 63⁰
Thus, at the end of the walk, the person's resultant displacement is 495.1 m at 63⁰ south of west.
