Note on above video: there are other ways of dealing with angled walls. I (unlike Mr Bicen) like to use unit vectors to rewrite vectors as parallel and perpendicular to a wall, both approaches are perfectly valid.

You can determine the magnitude of a vector in a given direction by applying the scalar product with the unit vector in the required direction.

A key point in both cases is that the impulse always acts perpendicularly to a wall (and you can therefore use I=m(v-u) in vector form to work this out first. Finding the direction of the impulse is often a key first step.
