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 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 .

What is the maximum speed at which a car can turn round a curve of 30 m radius on a level road if the coefficient of friction between the types and the road is 0.4 .(Given, acceleration due to gravity = 10 ms ^(-2)

A cyclist speeding at 18 km h^-1 on a level road makes 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?

A car is negotisting a curved road of radius R . The road is banked at an angle theta. The coefficient of friction between the tyres of the car and the road is mu_(s) . The maximum safe velocity on this road is:
