    Solution

    A bus moving along a circular track is an example of accelerated or non-inertial frame of reference. A frame of reference which is accelerating with respect to an inertial frame of reference is called non-inertial frame of reference. The bus is a non-inertial frame of reference. This is because the direction of bus is continuously changing and hence, it's velocity is also changing. Hence acceleration is changing.
