What should be the coefficient of friction between the tyres and the road, when a car travelling at `60 km h^(-1)` makes a level turn of radius `40 m` ?

A car moves at speed of 36 km hr^-1 on a level road. The coefficient of friction between the tyres and the road is 0.8 . The car negotiates a curve of radius R. IF g=10 ms^-2 , then the car will skid (or slip) while negotiating the curve if the value R is

(a) Find the maximum speed at which a car turn round a curve of 30 m radius on a level road if the coefficient of friction between the tyres and the road is 0.4 [ acc. Due to gravity = 10 m // s^(2) ] (b) For traffic moving at 60 km/hr , if the radius of the curve is 0.1 km , what is the correct angle of banking of the road ? ( g = 10 m // s^(2))

A car is travelling along a curved road of radius r. If the coefficient of friction between the tyres and the road is mu the car will skid if its speed exceeds .

A cyclist speeding at 18 km// h on a level road takes a sharp circular turn of radius 3 m without reducing the speed . The coefficient of static friction between the tyres and the road is 0.1 Will the cyclist slip while taking the turn ?
