Consider a circular road of radius 20 meter banked at an angle of 15 degree. With what speed a car has to move on the turn so that it will have safe turn?

Figure shows a 11.7 ft wide ditch with the approach roads at and angle of 15^0 with the horizontal. With what minimum speed should a mororbike be moving on the road so that it safely croses the ditch? Assume that the length of thebike is 5 ft, and it leaves the road when the front part runs out of the approch road.

The road at a circular turn of radius 10 m is banked by an angle of 10^0 . With what speed should a vehicle move on the turn so that the normal contact force is able to provide the necessary centripetal force?

A circular road of radius 50 m has the angel of banking equal to 30^0 . At what speed should a vehicle go on this road so that the friction is not used?

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.

A car of mass 1500 kg is moving with a speed of 12.5 ms^(-1) on a circular path of radius 20 m on a level raod what should be the frictional force between the car and the raod so that the car does not slip what should be the value of the coefficent of friction to attain this force
