To find the minimum coefficient μs of static friction between the road and the car, we need to equate the centripetal force (Fc) to the maximum static friction force (fs). Rearranging the equation, we have μs = Fc / N = fs/mg. Substituting the values given, we can calculate the value of μs.Find the vertical component of the force that the cliff face exerts on the climber's feet.
