A car is driven round a curved path of radius `18m` without the danger of skidding The coefficeient of friction between the tyres of the car and the surface of the curved path is 0.2 What is the maximum speed in kmph of the car for safe driving ? `(g =10 ms^(-2))` .

Text Solution

Verified by Experts

`"Maximum speed."v=sqrt(mu_(s)gr)`
`v=sqrt(0.2xx10xx18)=sqrt(36)=6ms^(-1)`
