Consider a circular turn on a highway, where angle of banking is more than angle of repose. A car on this turn can move with a constant speed ${\nu }_0$  without help of friction.  Taking advantage of friction it can achieve a maximum speed ${\nu }_{\max }$ but cannot reduce its speed lower than a minimum speed ${\nu }_{\min }$. Which of the following conclusions can you draw from the given information ($g=10m/s^2$ )
