How Do You Determine George's Direction Relative to John in a Strawberry Field?

Click For Summary
SUMMARY

The discussion focuses on determining George's direction relative to John in a geometric context involving vectors. John is positioned at coordinates (-16, 0), while Paul is at (31.086, -25.173) after calculating his position based on George's distance and angle from Paul. The final coordinates for George are (15.086, -25.173), leading to a distance of 29.35 meters from John. The solution emphasizes the importance of visualizing the problem through geometric representation.

PREREQUISITES

Homework Statement



John, Paul, and George are standing in a strawberry field. Paul is 16.0 m due west of John. George is 40.0 m from Paul, in a direction 39.0 ∘south of east from Paul's location.

A. How far is George from John? (Already Done)

B. What is the direction of George's location from that of John?

Homework Equations

The Attempt at a Solution


I did part A which is shown below, but how do I get part B?

John = -16i

i = (40)cos(39) = 31.086
j = (-40)sin(39) = -25.173

Paul = 31.086i -25.173j

G = P+J = (-16i)+(31.086i -25.173j)
= (15.086i - 25.173j)
= sqrt((15.086)^2+(-25.173)^2)
Part A = 29.35
