Airplane and Wind Vector question

Click For Summary

Homework Help Overview

The problem involves an airplane flying due south at a speed of 500 km/h while being affected by a wind blowing from the southwest at 100 km/h. The objective is to determine the airplane's velocity relative to the ground and the deviation from its intended course after 10 minutes without corrective action.

Discussion Character

  • Exploratory, Assumption checking, Problem interpretation

Approaches and Questions Raised

  • Participants discuss the initial setup of the problem, including drawing diagrams and using trigonometric functions to resolve the wind's velocity into components. Questions arise about the next steps after calculating the wind's effect on the airplane's course.

Discussion Status

The discussion includes attempts to clarify the approach to finding the resultant velocity and how to calculate the airplane's course deviation over time. Some participants express uncertainty about the next steps and seek further guidance.

Contextual Notes

There is mention of a lack of responses to questions, which has impacted one participant's engagement with the course material.

Homework Statement



An airplane is heading due south at a speed of 500 km/h. If a wind begins blowing from the southwest at a speed of 100 km/h, calculate the velocity of the plane relative to the ground, and how far off course it will be after 10 min. if the pilot takes no corrective action.

Answer: 435 km/h, 9.36 degrees east of south


Homework Equations



x = hypotenuse * cos(45)
x = 100 km/h * cos(45)

y = hypotenuse * sin(45)
Y = 100 km/h * sin(45)

The Attempt at a Solution



First I drew a diagram with N, E, S, W labeled. I then drew a line going NE since the wind is coming from SW. Then using the same starting point as the wind I drew 500 km/h going south to represent the airplane. I now wrote in a 45 degree angle for the wind. From this point I made a right triangle for the wind. To find the x and y I used sin and cos to get the values y = 70.71 km/h and x = 70.71 km/h. Am I on the right track or no?

That's one good way to start. What next?
 
I am stumped. Where do I go from here?
 
After you get your velocity how do you find how the course of the plane movd in five minutes??
 
I don't know. I never got a reply and ended up dropping the course without having to pay for it fortunately.
