Let v⃗ a be the velocity of the car at point a. what can you say about the acceleration of the car at that point?

Answer and Explanation:

Let the velocity of the car at a point is A is v

We have to tell about the acceleration at that point

Acceleration at that point will be perpendicular to the velocity and directed inside of the track

We can tell anything about the magnitude of the acceleration as magnitude of acceleration is the rate of change of velocity and here we have no information about time

some think that theories become laws, but theories and laws have separate and distinct roles in the scientific method. a law is a description of an observed phenomenon in the natural world that hold true every time it is tested. it doesn't explain why something is true; it just states that it is true.
