Vectors: If a bird flew at 30kmh-1 at a bearing of 65 degrees but...

[JRoomer]

Hi all,

I have a vector question:

If a bird flew at 30kmh^-1 at a bearing of 65 degrees but there was a strong wind blowing of 10kmh^-1 from the south east - how do you express the velocity of the bird whilst taking into account the wind (in component form)? And then can you calculate the resultant velocity of the bird from that equation?

Thanks,
Abbie

Did you draw a sketch approximating the flight of the bird?

I did. Should I be getting a triangle due to the flight of the bird meeting the wind from the s-east? Then do I need to calculate the angle from the s-east? I'm confused.

To create a triangle do you mean? Can you show an example? I'm confused how you would find the figures for the equation
