A car negotating 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_0`. The maximum safe velocityb on this road is:

A

`sqrt(g/R^2( mu_s + tan theta)/(1-mu_s +tan theta)`

B

`sqrt(g R^2( mu_s + tan theta)/(1-mu_s +tan theta)`

C

Direction of frictional force between wheel of the car and road is

What is the stopping distance for a vehicle of mass m moving with speed v along a level road, if the co-efficient of friction between the tyres and the road is mu ?

Find the maximum speed at which a car can turn round a curve of 36 m radius on a level road. Given the coefficient of friction between the tyre and the road is 0.53.

A car has to move on a level turn of radius 45 m. If the coefficient of static friction between the tyre and the road is mu_s=2.0, find the maximum speed the car can take without skidding.

In the section 3.7.3 (Banking of road) we have not included the friction exerted by the road on the car. Suppose the coefficient of static friction between the car tyre and the surface of the road is mu_s , calculate the minimum speed with which the car can take safe turn? When the car takes turn in the banked road, the following three forces act on the car. (1) The gravitational force mg acting downwards (2) The normal force N acting perpendicular to the surface of the road (3) The static frictional force f acting on the car along the surface.
