Rotation problem? (1 Viewer)

A car traveling on a flat circular track accelerates uniformly from rest with a tangential acceleration of 1.7m/s^2. The car makes it one quarter of a way around the circle before it skids off the track, Determine the coeficient of static friction between the car and track?

I really have no clue at all at how to go about this problem, any pointers or hints would be great. Thank you very much
 
It will skid at that moment when the radial force(centripetal force) will exceed the static frictional force
