What about the kinectic friction between the road and the tyres ?

A racing track of curvature 9.9m is banked at tan^-1 0.5 . coefficient of static friction between the track and the tyres of a vehicle is 0.2 . Determine the minimum and maximum speed of the vehicle.

A racing track of curvature 9.9m is banked at tan^-1 0.5 . coefficient of static friction between the track and the tyres of a vehicle is 0.2. Determine the speed limits with 10% margin.

The maximum speed with which a vehicle can negotiate a cuved road, which is banked at the angle theta=tan^-1(0.24) is 54 km//hr . IF the same road is flat and vehicle has to negotiate the curve with same maximum speed, the coefficient of friction between the road and tyres of the vehicle should be

Calculate the optimum speed and maximum speed of a four wheeler travelling along a curve track of radius 80 m. If the road is banked at an angle of 21^@ 48' and the coefficient of friction between the tyres and the road is 0.5.

For a truck with 14 tyres, only rear 8 wheels are power driven and can produce acceleration. These 8 wheels support half the entire load. If the coefficient of friction between road and each tyre is 0.6, the maximum attainable acceleration by this truck would be (Acceleration due to gravity = 10 ms^-2 )

A 100 kg car is moving with a maximum velocity of 9 m//s across a circular track of radius 30 m . The maximum force of friction between the road and the car is

Consider a car moving along a straight horizontal road with a speed of 36 km/h. If the coefficient of static friction between road and tyers is 0.4, the shortest distance in which the car can be stopped is (Take g=10 m//s2)

A plank with a box on it at one end is gradully raised about the other end. As the angle of inclination with the horizntal reaches 30^(@) , the box starts to slip and slide 4.0m down the plank in 4.0s . The coefficients of static and knitic friction between the box and the plank will be, respectively.

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 ?
