i cant get this no matter what i try;

A curve of radius 40 m is banked so that a 1070 kg car traveling at 60 km/h can round it even if the road is so icy that the coefficient of static friction is approximately zero. The acceleration of gravity is 9.81 m/s


a)Find the minimum speed at which a car can travel around this curve without skidding if the coefficient of static friction between the road and the tires is 0.7.
Answer in units of m/s

b)Find the maximum speed under the same
conditions. Answer in units of m/s.
