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

60

B

30

C

15

D

25

Text Solution

Verified by Experts

The correct Answer is:
B
(b) For negotiating a circular curve on a levelled road, the
maximum velocity of the car is `v_(max) = sqrt(murg)`
Here`mu = 0.6, r = 150m,g = 9.8`
`:. V_(max) = sqrt(0.6xx150xx9.8)~= 30m/s`
