Wh000t stuck, I'd really be very much over the moon if someone helped me. Physics is really starting to grind me down. So here be the problem ladies and gents.

A light aircraft flying at 50ms-1 due north (bearing 000) is blown off course by a wind with a velocity of 30ms-1 which is blowing from the south west (bearing 225)

A) What is the velocity of the plane as seen by an observer on the ground?

B) At a particular instant the plane is directly over a marker. How far away from this position is the place 5 minutes later?

This is rather simple Vectors using Pythagoras.

And I don't want to insult you by showing you how to do Pythagoras smile.gif

I just have no idea where to start and how to approch the question. Once I know what to do it's alright, I can sorta figure my way around it, but trying to understand the wording and what they want me to do tottaly confuses me...

eh yeah...in retrospect this was a pretty stupid question all together.

I think that, as well as using Pythagoras, you could also draw a vector diagram to work out the question.
