A vehicle of mass m is moving on a rough horizontal road with momentum P. If the coefficient of friction between the tyres and the road be m, then the stopping distance is [CBSE PMT 2001]

• A.             \[\frac{P}{2\mu \,m\,g}\]        
• B.             \[\frac{{{P}^{2}}}{2\mu \,m\,g}\]
• C.             \[\frac{P}{2\mu \,m{{\,}^{2}}g}\]  
• D.             \[\frac{{{P}^{2}}}{2\mu \,m{{\,}^{2}}g}\]
