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.

Find the maximum speed at which a car can turn round a curve of 36 m r

1.	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.
Answer» Solution :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)`
