The minimum velocity (in ms^(-1))` with which a car driver must traverse a flat curve of radius 150m and coefficient of friction 0.6 to avoid skidding is

A

30

B

25

C

60

D

15

Text Solution

Verified by Experts

The correct Answer is:
A
`(mv ^(2))/(r ) =F = mu R = mu mg `
` therefore v^(2) = mu r g `
` therefore v= sqrt( mu r g ) = sqrt( 0.6 xx 150 xx10 ) = 30 m//s `
