Urgent - trajectory problem to solve!

  1. Oct 30, 2007 #1
    1. The problem statement, all variables and given/known data

    I have to calculate disctance that body(for example a jumper) that jumps of a slope at 45 degrees with initial speed of 20 m/s and under 15 degrees.
    2. Relevant equations
    x=Vox * t
    y=Voy*t - 1/2*g*t*t

    y=ax + b, b=0 => y=ax

    3. The attempt at a solution

    I don't know where to start. I can solve a simillar example where body has been shot from a building with a certain initial speed and under under 30°. It is simillar to this picture, but here it is difference that we shoot from a slope and we don't know at what height we only know that slope is placed under 45° with a surface.
