Q. Find the maximum velocity for skidding for a car moved on a circular track of radius $100\ m.$ The coefficient of friction between the road and tyre is 0.2
A) $0.14\ m/s$
B) $140\ m/s$
C) $1.4\ km/s$
D) $14\ m/s$
Explanation
(d) $v_{\max} = \sqrt{\mu rg} = \sqrt{0.2 \times 100 \times 9.8} = 14m/s$
