1. The problem statement, all variables and given/known data A race car starts from rest on a circular track. The car increases its speed at a constant rate 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. 2. Relevant equations ... :( 3. The attempt at a solution The problem is I don't even know where to start. I'm not looking for a quick answer from you all; I want to know how I should approach this and build some skillz!
