Question

(ii)Is there any change in the acceleration on the vehicles from the initial point to the final point
that are moving on it? Explain.

Answer 1

Solving for Final Position with Constant Acceleration

Answer 2

Yes, there is a change in the acceleration on the vehicles from the initial point to the final point  that are moving on it

Explanation:

If I were driving a car in a circle at a constant speed of 20 mi/hr, then the speed is neither decreasing nor increasing; therefore there must not be an acceleration." At the center of this common student misconception is the wrong belief that acceleration has to do with speed and not with velocity. But the fact is that an accelerating object is an object that is changing its velocity. And since velocity is a vector that has both magnitude and direction, a change in either the magnitude or the direction constitutes a change in the velocity. For this reason, it can be safely concluded that an object moving in a circle at constant speed is indeed accelerating. It is accelerating because the direction of the velocity vector is changing.
