A small aircraft, on a heading of 225 degrees, is cruising at 150km/h. IT is encountering a wind blowing from a bearing of 315 degrees at 35km/h. Determine the aircraft's ground velocity.

Question

not physics

anonymous · Answer

Vector addition?

nottim · Answer

application of vector addition, yah.

anonymous · Answer

Draw it out. 
Find it's components. 
Add their x componants and y componants separately. 
Put them back together in a triangle.

nottim · Answer

i somehow figured out how to get resultant, but not the angle...

nottim · Answer

im not suppose to use component method

anonymous · Answer

Use tan(y/x)

anonymous · Answer

Oh I see. THen I'm afraid I can be of no help to you.

nottim · Answer

ok...oh well. thx u

radar · Answer

draw it out, and remember when directions are concerned, 0 degrees is North.

nottim · Answer

i did....but i didnt draw it here. i got the magnitude, but not the angle.
i think though that i might have read the answer wrong...im still double checking again. but thank you

nottim · Answer

yeah, i forgot it was bearings

radar · Answer

O.K, good luck on this problem it is a good question

radar · Answer

Oh yes, note that the wind is FROM a bearing of 315 degrees in other words the force is towards E 45 S.

radar · Answer

Note also the angle between the aircraft and the wind vector is 90 degrees.  as aircraft is flying on a bearing of W 45 S

nottim · Answer

hey, radar, i got 13.1 degrees (not considering bearings), as the angle between the resultant and the aircraft's cruising speed. Um. What should I do with that?

nottim · Answer

@Radar Hey....do you have time? I need you to please revisit this...
