The discussion revolves around determining the direction of a person walking a specific distance north and east, specifically 3.0 km north and 4.0 km east. The subject area pertains to basic trigonometry and vector analysis in physics.
Some participants have provided guidance on using the tangent function to calculate the angle, while others confirm the wording of the problem. There is an ongoing exploration of the calculations involved, but no consensus has been reached regarding the correctness of the angle derived.
One participant notes that the question was worded exactly as it appears in the textbook, which may imply constraints on how the problem can be approached or interpreted.
Hello oG riT. Welcome to PF !oG riT said:what is the direction of a person that walks 3.0-km North and 4.0-km East?
and can you tell me how you got the answer please
Ace. said:Use Tan function to find the angle.
(θ represents an angle)
Tanθ = opp/adj
= 4km / 3km
θ = tan-1(4km/3km)
So the direction would be [N θ E]
