A vehicle of mass m is moving on a rough horizontal road with momentum

1.	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
Answer» `p/(2 MU m g)` `(p^2)/(2 mu mg)` `(p)/(2 mu m^2g)` `(p^2)/(2 mu m^2g)` Solution :STOPPING DISTANCE = `(1/2(mv^2))/(mu mg)` `= (1/(2m) xx m^2v^2)/(mu mg) = (p^2)/(2 mu m^2 g)`.
