Explain why a car travelling on a level road with coefficient of friction p. can never have an acceleration greater ±an pig.

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

A car moves with constant velocity along a straight level and frictionless road .draw the acceleration time graph.

A particle inside a hollow sphere of radius r, having coefficient of friction (1/ √3 ​ ), up to what height can particle be at rest?

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.

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.

Two car travelling each other on a straight road at velocity 10m/s and 12m/s respectively . When they are 150 m apart , both drivers apply their brakes and each car decelerates at 2m/s^2 until it stops . How far apart will they be when they have both come to stop?

The maximum speed that can be achieved without skidding by a car on a circular unbanked road of radius R and coefficient of static friction p is

Explain C_P and C_V . Which is greater and Why ?
