A car is moving along a straight horizontal road with a speed ${\mathrm{u}}_0$.If the coefficient of friction between the tires and the road is $\mathrm{\mu }$, the shortest distance in which the car can be stopped is 

• A

  $\frac{u_{\mathrm{o}}^2}{2\mathrm{\mu g}}$

• B

  $\frac{{\mathrm{u}}_0}{\mathrm{\mu g}}$

• C

  ${\left(\frac{{\mathrm{u}}_0}{\mathrm{\mu s}}\right)}^2$

• D

  $\frac{{\mathrm{u}}_0}{\mathrm{\mu }}$
