SUMMARY

The discussion focuses on calculating the resultant velocity of a bird flying at 12.6 m/s heading 27.7° west of north, while accounting for a wind speed of 8.95 m/s blowing at 12.5° south of west. Participants emphasize the importance of vector addition and suggest that sharing the user's calculations could help identify errors. The conversation highlights the necessity of breaking down vectors into their components for accurate results.

PREREQUISITES
  • Understanding of vector addition and components

Homework posted in wrong forum, so no template
A bird is flying through the air with an air speed of 12.6 m/s heading 27.7° west of north. It is a windy day with the wind blowing at 8.95 m/s heading 12.5° south of west. What is the velocity of the bird as seen by a person on the ground?
Note: I keep doing this question but my answer (the resulting vector) don't come out correct. Any help is appreciated.

Looks like regular vector addition to me. Maybe if you post your attempt we could help you spot what went wrong
 
Yes, please show your working, even though you know it's wrong. Someone here can probably point out your error(s).
