The minimum velocity (in ms⁻¹) with which a car driver must traverse a flat curve

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

Options

(a) 60 ms⁻¹
(b) 30 ms⁻¹
(c) 15 ms⁻¹
(d) 25 ms⁻¹

Correct Answer:

30 ms⁻¹

Explanation:

Using the relation,
or v² = μrg
= 0.6 x 150 x 10
v = 30 ms⁻¹.
