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.
