A vehicle of mass M is moving on a rough horizontal road with a momentum P. If the coefficient of friction between the tyres and the road is mu, then the stopping distance is

Answer»

<P>`(P)/(2muMg)`
`(P^(2))/(2muMg)`
`(P^(2))/(2muM^(2)G)`
`(P)/(2muM^(2)g)`

Solution :`P=mv, v^(2)-U^(2)=2as, a =mu_(k)g`
