What is the maximum velocity with which a vehicle can negotiate a turn of radius r safely when coefficient of friction between tyres and road is `mu` ?

A road is banked correctly for a speed of 40 kmph. What is the maximum speed with which a car can negotiate the bend without skidding if the coefficient of friction between road and tyre is 0.3 and radius of the bend is 1 km ? [Hint : v_(m)^(2)=v^(2)+mu gr ]

Find the maximum speed with which a car be safely driven along a curve of radius 100 , . If the coefficient of fricition between its tyres and the road is 0.2.

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)

Find the maximum speed at which a car can turn round a curve of 30 m radius on a level road if coefficient of friction between the tyress and road is 0.4. Take g = 10 m//s^(2) .

What is done to increase friction between the tyres and road ?

What would be the maximum speed of a car on a road turn of radius 30 m, if the coefficient of fraction between the types and the road is 0.4 ?

The maximum speed of a car which can be safely driven along a curve of radius 10 m , If the coefficient of friction between the tyres and the road is 0.5, is (g=9.8 m//s^(2))

What is the maximum speed with which a car safely turn a around a curved horizontal road of radius 50 m ? [The coefficient of friction between the tyres and the surface of the road is 0.4 ]

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) .
