Beer mug across counter direction of mugs velocity

Homework Statement


In a local bar, a customer slides an empty beer mug down the counter for a refill. The bartender is momentarily distracted and does not see the mug, which slides off the counter and strikes the floor at distance d from the base of the counter. The height of the counter is h. With what speed did the mug leave the counter? Which I got Vinitial=d/sqrroot(2h/g). Now my question is what was the direction of the mugs velocity just before it hit the floor?


Homework Equations





The Attempt at a Solution


Would I have to break something up into components?

Splitting it into perpendicular components seems like an excellent idea :approve:.
