When a body moves with some friction on a surface

For a body on a horizontal surface, coefficients of static and kinetic frictions are 0.4 and 0.2 respectively. When the body is in uniform motion on the surface, a horizontal force equal in magnitude to limiting friction is applied on it. The acceleration produced is

A body of mass m moves with a velocity v on a surface whose friction coefficient is mu . If the body covers a distance s, before it comes to rest, then v will be :
