Determine the maximum speed at which a car can trun round a curve of 30 m radius on a level road, if the coefficient of friction between the tyres and the road is `0.4`.

Text Solution

Verified by Experts

Here centripetal force is provided by friction so,
`(mv^(2))/(r)le mumg Rightarrow v_("max")=sqrt(murg)=sqrt(120)approx11ms^(-1)`
