A car is initially at rest. It starts mvoing with tangential acceleration a_tan along a flat circular track of radius r. If the coefficient of static friction is mu, determine the total distance traveled by the car before it skids off the track. This is what I did. I drew the free body diagram with normal force point up, mg pointing down, and f point right, and acceleration (not on the diagram) is pointing left towards the center. Is this the correct diagram? I know N=mg and F = ma F = m (v^2)/r so v=SQRT(Fr/m) I know d = (1/2)at^2 Where do I go from here to find the distance. I don't have acceleration and time.
