Friction : impulsive or non impulsive?

    Maximum value of friction depends upon the normal reaction and normal reaction can be impulsive, so does that imply friction can be impulsive?

    Sure. A couple of examples that spring to mind are the application of "English" to the cue ball on a pool table and the behavior of a spinning rubber ball as it bounces.

    Edit: And the application of topspin to a tennis shot as the racket hits the ball.

    There are a bunch of different kinds of friction. It depends on the surfaces, forces, and definitely the impulses. If you account for pressure drag as a part of friction, it's kinda like skipping a rock.
