IF the man is running at 120 metres/hr stays directly below the bird, what does that say about the horizontal component of the birds velocity? Given this and the angle, can you find it's actual velocity?

edit: sorry, I shouldn't really have helped withour seeing your efforts first-PF rules.. I don't know what came over me!! In future please use the homework posting template with which you were provided.
