The maximum speed for the overturn of a car moving on a circular track is given by,
v=underroot(co-efficient of friction X radius X acceleration due to gravity)
v=underroot(0.2 X 100 X 9.8)
v=14m/s.
v=underroot(co-efficient of friction X radius X acceleration due to gravity)
v=underroot(0.2 X 100 X 9.8)
v=14m/s.

But the distance covered by the car is the circumference of a circle.

(co-efficient of friction X radius X acceleration due to gravity).
Can I know how this formula has been derieved.
Can you please explain this formula?

9. 8 where it came from?

9.8 comes from the g, which is gravitational constant.

We Know that, force F=m.a; mu.m.g = m.a
That implied, a = mu.g
Again, v2 - u2 = 2.a.s
v2 = 2. mu. g. s
v2 = sqrt(2. mu. g. s)
Where, m=mass, a= acceleration, mu=co-efficient of friction, g=acceleration due to gravity, s=distance, v=final speed and u=initial speed.

@Bhavy.
9.8 is the acceleration due to gravity not the gravitational constant.
Gravitational constant=6. 67x10 to the power -11 N m*m/kg*kg.
