We don't really know the mass of the car. But, see if you can deduce the mass by toggling the information button and looking at the size of the inward force needed for the car to round the corner.
(Hint: just use Newton's Second Law)
Now that we know the mass of the car as well as the magnitude of the inward force required to push the car around the corner, we can say something about the size of the frictional force and the minimum coefficient of static friction required to do this.
