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 $\mu$, then the stopping distance is
$\frac{P}{{2\mu \,m\,g}}$
$\frac{{{P^2}}}{{2\mu \,m\,g}}$
$\frac{P}{{2\mu \,m{\,^2}g}}$
$\frac{{{P^2}}}{{2\mu \,m{\,^2}g}}$
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 $\mu$, then the stopping distance is
$$ $S = \frac{{{u^2}}}{{2\mu g}} = \frac{{{m^2}{u^2}}}{{2\mu g{m^2}}} = \frac{{{P^2}}}{{2\mu {m^2}g}}$
