Question

A cyclist speeding at 18 km h⁻¹ on a level road takes a sharp circular turn of radius 3 m without reducing the speed and without bending towards the centre of the circular path. The coefficient of static friction between the tyres and the road is 0.1. Will the cyclist slip while taking the turn? 

Answer 1

Given: v = 18 km/h = 18 × 5/18 = 5 m/s,

r = 3 m, µ = 0.1 

To find: Whether the cyclist can take the turn or not without slipping

Formula: Maximum safe speed of cyclist
