Calculating the Speed of a Bird Flying at an Angle

[shehri]

Hi friends,
Plz. point me how to find the following:

A man on the ground sees a bird flying at angle of 60 degrees with horizontal.He started running at 120m/hour,is able to stay directly below the bird.What's bird speed?

Thanks in advance.

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.
