This problem seems to be reoccuring, and I am pretty sure it will be on my test on friday.

This is the question:

"A race car starts from rest on a circular track. The car increases its speed at a constant rate a(sub i) as it goes once around the track. Find the angle that the total acceleration of the car makes - with the radius connecting the center of the track and the car - at the moment the car completes the circle."

Now I understand some aspects of the question, like this is a Tangential and Radial acceleration problem. But what I am looking for is a sort of guide through these types of problems, so I can tackle any problem that is like this.

Also, the question on my quiz was this, but it asked different types of questions about the circle. I will get it back tomorrow and post the variation.

Thank you very much.
