A road is banked at an angle of `30^(@)` to the horizontal for negotiating a curve of radius `10 sqrt(3)` m. At what velocity will a car experience no friction while negotiating the curve? Take `g=10 ms^(-2)`

A motorcyclist of mass m is to negotiate a curve of radius r with a speed v . The minimum value of the coefficient of friction so that this negotiation may take place safely, is

The slope of the smooth banked horizontal road is rho .If the radius of the curve road is 'r' then the maximum velocity with which a car can negotiate the curve will be

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

The slope of the smooth banked horizontal road is rho . If the radius of the curve road is 'r' , them the maxiumum velocity with which a car can negotiate the curve will be

The maximum frictional force between the tyres of a car and the road is 0.5 mg. the car negotiates a curve of radius 10 metre. The velocity is

The maximum frictional force between the tyres of a car and the road is 0.5 mg. the car negotiates a curve of radius 10 metre. The velocity is

Find the maximum speed at which a car can take turn round a curve of 30 cm radius on a level road if the coefficient of friction between the tyres and the road is 0.4. Take g = 10 ms^(-2) .
