The angular speed remained constant after twelve turns at 11 rad/s.
Explanation:
As per the Newtons equation of motion, the final velocity can be determined by using the below equation, provided ,the displacement and acceleration with initial velocity is given.
[tex]v^{2}= u^{2}+2as[/tex]
Since, the present case follows circular motion, the displacement will be equal to angular displacement. And the velocity is equal to angular velocity.
As the car revolves complete twelve turns, then the displacement will be zero, since the final position is equal to the initial position.
So,
[tex]v^{2}= (11)^{2}+2*22.2*0\\\\v = 11 rad/s[/tex]
Thus, the angular speed remained constant after twelve turns at 11 rad/s.
