Can't Get Started. Please Help! The following question I have spent the past few hours trying to figure out how to solve it. I'm not sure where to start. Question: A car traveling on an flat (unbanked) circular track accelerates uniformly from rest with a tangential acceleration of 1.70 m/s^2. The car makes it one quarter of the way around the circle before it skids off the track. Determine the coefficient of static friction between the car and track from these data. I have been looking through the corresponding section in the text to this question for an understanding/example solution/equations but I'm not seeing anything that helps me. Anyone have an idea?
