What angle should the bird head?

AI Thread Summary
To determine the angle a Canada goose should fly to maintain a direct southward path against a 34 km/h east wind while flying at 100 km/h, vector analysis is required. The calculation involves finding the resultant angle relative to the north-south direction, leading to an angle of approximately 19.9 degrees east of south. The discussion highlights the importance of understanding vector components and their application in real-world scenarios. Additionally, the flying speed of 100 km/h for Canada geese was confirmed as accurate. Mastery of vector concepts is emphasized for solving such problems effectively.

Homework Statement


Canada geese migrate essentially along a north-south direction for well over a thousand kilometers in some cases, traveling at speeds up to about 100 km/h. The one goose is flying at 100 km/h relative to the air but a 34 km/h wind is blowing from west to east.

At what angle relative to the north-south direction should this bird head to travel directly southward relative to the ground?

Homework Equations

The Attempt at a Solution


Set it up the following way and got about 70.1, subtracted that from 90 and got 19.9. Can somebody check my work to make sure I did it correctly?

Do you know anything about vectors?
 
We're currently learning vectors right now, but I've been struggling with it because of angles and the mess of formulas. I'm just not sure how to place the vector for the 100 km/h bird.
 
Looks like you got it.
 
Just in case you have to enter this in a computer or something: they ask for the angle wrt north-south, not for the angle wrt west...
 
I thought a flight speed of 100 km/h for a Canada goose was preposterous, until I looked it up... :))
 
Thread 'Voltmeter readings for this circuit with switches'
TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...
Thread 'Struggling to make relation between elastic force and height'
Hello guys this is what I tried so far. I used the UTS to calculate the force it needs when the rope tears. My idea was to make a relationship/ function that would give me the force depending on height. Yeah i couldnt find a way to solve it. I also thought about how I could use hooks law (how it was given to me in my script) with the thought of instead of having two part of a rope id have one singular rope from the middle to the top where I could find the difference in height. But the...
