## Homework Statement

Calculate the angular acceleration and angular velocity of a 4 kg object rotating in a circle of 3 m radius in a time of 6 s.

## Homework Equations

## The Attempt at a Solution

Angular acceleration = ω2*r

C=2∏r= 2*3.14*3=18.84

360°/57.3°=6.28 rad/s

6.28/6= 2.09 rad/sec

Angular acceleration= (2.09)2*3=12.54???????

Angular velocity= angular displacement/time ????

I just want to check whether my working is correct or not.
