# How long is this area in the air?

I understand what they are asking me in these problem but I dont know how plug these numbers in the equations.
If you could help me it would be wonderful thanks.
Fc if spun on a 2.5m string at 6 radians every 10 seconds?

An arrow is shot at 20 m/s at an angle from the horizontal of 37 degree.what its maximum height? time in the air?Horitzontal range

tangential velociy if rotational frequency=0.75 Hz with a readius of 4.0m

Angular accerlation if change from 10rad/pie to stopped in 3.0 seconds?

Um, no offense but I don't really understand anything you just said, could you make it a bit more clear?
