Find the maximum speed at which a car can turn round a curve of 36 m radius on a level road. Given the coefficient of friction between the tyre and the road is 0.53.

Explanation

Radius of the curve r= 36 m
Coefficient of friction `mu` = 0.53
Acceleration due to gravity `g= 10 ms^(-2)`
`v_(max) = sqrt(mu rg) = sqrt( 0.53 xx 36 xx 10 ) = 13.81 ms^(-1)`
