Hello lovelycecila!

It seems from the date you provided, and what result you want, that what you meant was "Orbital Velocity" rather than "angular velocity" .

On PF it is required that you show us some working and a reasonable attempt before we can offer any real help. We don't do the homework for you, after all. Think perhaps of some relevant equations, that should definitely help.
