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.
The Attempt at a Solution
Angular acceleration = ω2*r
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.
