One more HW question, if you see this in time

Consider a ball that was launched horizontally from a rooftop.  The initial height above the ground was 15-m.  It landed 20-m from the base of the building.  What was the initial speed of the ball?

One other thing to think about.  How would we go about dealing with launches at angles (which, of course, make up the bulk of projectile problems)?
