A racing car travels on a track (without banking) `ABCDEFA`.`ABC` is a circular arc of radius `2R. CD` and `FA` are straight paths of length `R` and `DEF` is a circular arc of radius `R = 100m`. The co-efficient of friction on the road is `� =0.1`. the maximum speed of the car is `50m s-1`. Find the minimum time for completing one round. .
