    Plane Wind
AI Thread Summary
To determine the angle a plane should orient to fly straight from point A to point B, considering a wind blowing 62 km/hr from east to west, the calculated angle is approximately 16.4 degrees. However, this angle must be specified in relation to a reference direction, such as true north. The second part of the question highlights that if the plane flies directly south, it will not reach point B due to the wind, indicating that the two scenarios yield different headings. Therefore, the initial assumption that both angles would be the same is incorrect. Accurate navigation requires accounting for wind direction and speed to ensure the plane reaches its intended destination.

Homework Statement
This was a two step question on my homework. I got the same answer for both so I think I got it wrong
Relevant Equations
Sin(@) = o/h Tan(@) = o/a
So the question was if a plane is going from point A (origin) to point B 400 km directly south of point A at 220km/hr north and there is a wind going 62 km/hr east to west, what angle should the plane orient to go straight from point A to point B? I got something lik 16.4 degrees. The second part was if the plane flies straight north to south, what angle will the plane be heading? Wouldn't the answer be the same for both?

16.4 degrees measured with respect to what? That is insufficient to specify direction. Same for the second part.

On edit:
Better yet, give the headings using the aviation convention of heading angle increasing clockwise from zero (due North) to 360° as shown in the picture below.

Sorta crappily stated question.

The two aren't the same : the first part implies the nose is not pointed due south (but it still flies due south), the second it is pointed due south (but will miss point B).

Welcome!
Could you post the full text as shown in the original question?
How could the airplane be “going from point A (origin) to point B 400 km directly south of point A at 220km/hr north”?

Its heading was recorded just as it was about to pass over the North Pole? :oldbiggrin:

...or...

The "62"km/hr wind is missing a zero. :woot:
 
Thread 'Collision of a bullet on a rod-string system: query'
In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
