    A vehicle of mass in is moving on a rough horizontal road with momentum P. If the coefficient of friction between the tyres and the road be\[\mu ,\] then the stopping distance is:

    A) \[\frac{P}{2\,\mu \,mg}\]           

    B)  \[\frac{{{P}^{2}}}{2\,\mu \,mg}\]

    C) \[\frac{P}{2\,\mu \,{{m}^{2}}g}\]                    

    D)  \[\frac{{{P}^{2}}}{2\,\mu \,{{m}^{2}}g}\]

    Correct Answer: D

    Solution :

     \[S=\frac{{{u}^{2}}}{2\mu g}=\frac{{{m}^{2}}{{u}^{2}}}{2\mu g{{m}^{2}}}=\frac{{{P}^{2}}}{2\mu {{m}^{2}}g}\]
