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 of a car which can be safely driven along a curve of radius 100 m and coefficient of friction between tyres and road is 0.2

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 will be maximum speed of a car on a road turn of radius 30 m, if the coefficient of friction between the tyres and the road is 0.4 ?

What will be the maximum speed of a car on a road turn of radius 30 m, if the coefficient of friction between the tyres and the road is 0.4? (Take g=9.8m//s^(2) )

The maximum speed of 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

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.

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))
