The maximum safe speed of a vehicle on a circulartrack is `15km//h` . When the track becomes wet, the maximum safe speed is `10 km//h` .The ratio of coefficient of friction of dry track to that o0f the wet track is

Themaximum safe speed of a vehicle ona circular track is 15 km/h. When the track becomes wet, the maximum safe speed is 10 km/h. The ratio of coefficient of friction of dry, track to that of the wet track is

On a dry road , the maximum permissible speed of car in a circular path is 12 ms^-1 . IF the road becomes wet, then the maximum speed is 4sqrt2ms^-1 . IF the coefficient of friction for dry road is mu , then that for the wet road is

On a dry road , the maximum permissible speed of car in a circular path is 12 ms^-1 . IF the road becomes wet, then the maximum speed is 4sqrt2ms^-1 . IF the coefficient of friction for dry road is mu , then that for the wet road is

On a dry road the maximum safe speed for a vehicle moving on a curved raod is 30 km/ hour , After heavy showers , the maximum safe speed for the same raod was 18 km/ hour . The ratio of the coefficient of friction for the dry road to that of wett road is

On a dry road, the maximum safe speed for a vehicle moving on a curved road is 39km/hr. After heavy showers the maximum safe speed for the same road was 18 km/hr.What is the ratio of the co-efficient of friction for the dry road to wet road ?

Write equation of maximum safe speed on level circular track

A person drives a car along a circular track on a level ground. Derive an expression for the maximum safe speed of the car.

Radius of level circular track is 20 m. If co­efficient of friction is 0.25, then what will be maximum safe speed ? (g = 9.8 ms^(2) )

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.
