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.

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