At what speed should a car enter a curve in order not to slip if the radius is 30 m and the coefficient of friction is 0.3? A mass of 2 kg sits on the edge of a rotating table at a distance of 3 m. The coefficient of friction is 0.15. What is the maximum speed the table can spin and the mass not slip off?

A road has a round hill 12.0 m in radius. What is the maximum speed at which a car can have and just stay on the road?
