The Attempt at a Solution


I believe that A is an acceptable answer, since the car is at a constant acceleration of zero.
My teacher says C is the only correct answer.

Thank you for your input!

I agree. The teacher seems to be entertaining the notion that the orbit of the moon is a perfect circle, which it ain't.

How the teacher can select C? Have you asked what is the reason?
