A circular road of radius 1000 m has banking angle `45^@`. IF the coefficient of friction is between tyre and road is 0.5, then the maximum safe speed of a car having mass 2000 kg will be

A circular road of radius 1000m has banking angle 45^@ . If the coefficient of friction between tyres and road is 0.5, the maximum safe speed of a car having mass 2000 kg will be

A motorcycle is travelling on a curved track of radius 500 m. If the coefficient of friction between the tyres and road is 0.5, then the maximum speed to avoid skidding will be

A circular racetrack of radius 300 m is banked at an angle of 15^@ . If the coefficient of friction between the wheels of a race-car and the road is 0.2, what is the (a) optimum speed of the race- car to avoid wear and tear on its tyres, and (b) maximum permissible speed to avoid slipping ?

A circular racetrack of radius 300 m is banked at an angle of 15^(@) If the coefficient of friction between the wheels of a race car and the road is 0.2 what is the (a) optimum speed of the race car to avoid wear and tear on its tyres , and (b) maximum permissible speed to aviod slipping ?
