Question

A car rounds an unbanked curve of radius 92 m without skidding at a speed of 26 ms⁻¹. The smallest possible coefficient of static friction between the tyres and the road is 


​

Answer 1

Answer:

The maximum speed at which a car can make a turn v =

The maximum speed at which a car can make a turn v = μ

The maximum speed at which a car can make a turn v = μ s

The maximum speed at which a car can make a turn v = μ s

The maximum speed at which a car can make a turn v = μ s rg

The maximum speed at which a car can make a turn v = μ s rg

The maximum speed at which a car can make a turn v = μ s rg =

The maximum speed at which a car can make a turn v = μ s rg = 0.75×60×9.8

The maximum speed at which a car can make a turn v = μ s rg = 0.75×60×9.8

The maximum speed at which a car can make a turn v = μ s rg = 0.75×60×9.8 =21m/s
