A race car is making a Uturn at constant speed. The coefficient of friction between the tires and the track is μs = 1.0. If the radius of the curve is 40 m, what is the maximum speed at which the car can turn without sliding? Assume that the car is performing uniform circular motion.

physics 
Hard to solve ..please help!!!!,
v=sqrt (m*g*r)
