Question

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

Options:

A . 0.14 m/s

B . 140 m/s

C . 1.4 km/s

D . 14 m/s

Answer: Option D
:
D

V_{m a x} = \sqrt{μ r g} = \sqrt{0.2 \times 100 \times 9.8} = 14 m / s
