A particular unbanked turn in the road is shaped like a circle with a radius of 30 meters. A car with a mass of 1500 kg can safely go around this turn at a maximum speed of 17 m/s. What is the coefficient of static friction between the car's tires and the road?

A car is travelling at the top or a semi-circular hill, and at the top of the hill, it is moving exactly at 32 m/s which is exactly the speed needed to just leave the road/hill. If the same car is travelling over a hill which is one quarter as tall (radius is one quarter), what is the maximum speed, in m/s, it can travel before it just starts to leave the hill?
