Default help me out here!!!

alright so im bored and im "studying" for finals, so ill let you see if you can figure out any of this stuff that i have to learn in a few hours time. I got a lot more, so if you happen to know this stuff and want to work your brain, dont be scared to ask..

lets see...

A .2kg ball is tied to a rope and swung around in the air in a circular path(like a lasso if you will) andits radius of rotation is .75 meters,

1) what isits angular velocity, 2)tangential velocity and 3)the tension force on the rope?

dont have too much fun!!!

the only cool thing about this physics class is that we get to build stuff like rockets and musical instruments, (sound waves and stuff) remote controll robots (electronics) out of scratch, so its cool sometimes.
