frictional impulse

BITSAT 2015 Sample Questions › Mechanics questions › frictional impulse

we know that friction can not propose motion, its just opposes it... is the same true for frictional impulse as well??
say if a body is moving in +ve x - axis nd a frictional impulse acts on the body towards left, then under any condition can it propose motion in -ve x- axis??

yes if the impulse is big enough to bring the body`s initial velocity to 0
