A curve of radius 30 m is banked so that a 950 kg car travelling at 40 km/h can go round it even if the road is so icy that the coefficient of static friction is approximately zero. You are commissioned to tell the local police the range of speeds at which a car can travel around this curve without skidding. Neglect the effects of air drag and rolling friction. If the coefficient of static friction is 0.3, what is...

A concrete highway curve of radius 84 m is banked at a 15.3 degree angle. What is the maximum speed with which a 1500 kg rubber-tired car can take this curve without sliding? First of all, what is the relevant coefficient of friction? (It's 1) What is the magnitude of the normal force acting on the car? What is the maximum speed the car can take this curve without sliding? Does this maximum speed depend on the mass of the...
