Homework Help: Beer mug across counter direction of mugs velocity

  1. Sep 5, 2008 #1
    1. The problem statement, all variables and given/known data
    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?

    2. Relevant equations

    3. 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:.

    hmmm, how did you get that equation for Vinitial? i am trying to sift through all these formulas and i just cant seem to get the correct one. :confused:
