Homework Help: Angle of impact ?

  1. Jun 17, 2015 #1
    1. The problem statement, all variables and given/known data

    A ball rolls off a table at speed v and impacts the floor at distance d.

    What is the angle between the path of the ball and a vertical line drawn at the moment of impact.

    2. Relevant equations

    I have derived from basic projectile motion formulae:

    Time of impact t = sqrt(2h/g)

    Distance d = Vox * sqrt(2h/g)

    Velcocity at impact = sqrt(Vox^2 - gt^2)

    3. The attempt at a solution

    I don't really know where to start, I believe I have all the required information above but how do I apply it ?

    Is this correct ?

    This is actually a mathematics topic question and should somehow relate back to vector calculus
