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.
