very basic problem

the problem is:
suppose the coefficient of statif friction between the road and the tires on a car is .60 and the car has no negative lift. what speed will put the car on the verge of sliding as it rounds a level curve of 30.5 m radius?
where do i even start with this? i have no idea what to do

Let the car's mass be m and its weight be (m)(g). Write the formula for the centripetal force needed to keep the car moving in a circle of radius 30.5 meters when the car has velocity v. (I assume you know the formula for centripetal (or centrifugal) force.) Set this equal to the maximum frictional force the tires can exert, which is (m)(g)(0.60) Solve for v.
