Snowboard jumping, hint/push in right direction

  1. Mar 8, 2010 #1
    1. The problem statement, all variables and given/known data
    A snowboarder knows to jump before reaching a downward slope.
    The launch speed of the jump is 38km/h and launch angle 9 degrees.
    The initial course is smooth and flat and the steeper track has a declining slope of 11.3degrees.

    a..
    If the snowboarder jumps before reaching the slope he lands on the top portion of the steeper track.
    In the landing find the angle between the snowboarders path and the slope.
    b..
    If the snowboarder jumps at the edge of the steeper track, how far below the launch level will he land and at what angle?
    2. Relevant equations



    3. The attempt at a solution

    So far im completely stumped on how to do this
    I've tried making vectors to describe the magnitude of the jump for part B by converting the velocity to m/s then using gravity as the downward force but they never end up making any sense.
    I don't really understand what the question means in part A "the angle between his path and the slope".
    I remember there being velocity formulas which involved angles but i cant find them in this text book.

    Would i be able to have a hint on how i can solve a and b?
    The formulas or first step or anything?
    The hardest part for me is getting started
    Thanks in advance
