    Answer:

    the angular velocity of the car is 12.568 rad/s.

    Explanation:

    Given;

    radius of the circular track, r = 0.3 m

    number of revolutions  per second made by the car, ω = 2 rev/s

    The angular velocity of the car in radian per second is calculated as;

    From the given data, we convert the angular velocity in revolution per second to radian per second.

    \omega = 2 \ \frac{rev}{s} \times \frac{2\pi \ rad}{1 \ rev} = 4\pi \ rad/s = 12.568 \ rad/s

    Therefore, the angular velocity of the car is 12.568 rad/s.
