Without changing the angle of banking, if we want to increase the maximum safe speed, with which a car can travel on the curved road by `10%` then what much we should increase the radius of curvature of the road from 20m.

What is the maximum velocity with which an automobile can move round a curved track banked at a angle of 30^@ having a radius of 10sqrt3 m(g=10ms^(-2)) ?

A car of mass 750 kg has an engine which produces a constant power of 40 kW. If the resistance to motion assumed constant is 800 N, Find the maximum speed at which the car can travel on the road. Also find the acceleration when it is travelling at 25m/s.

At what maximum speed a racing car can travel through unbanked curve of radius 50m?The coefficient of friction between tyres of car and road surface is 0.5

Find the maximum velocity with which a driver must drive his car on a flat curved road of radius of curvature 150m and co-efficient of friction 0.6, to avoid skidding of his car.

The circumference of a circular track is 1.256 km. What is the tangent of the angle of banking of the track if the maximum speed at which a car can be safely driven along it is 20m/s and g=10 m/s^2 ?
