Homework Help: Ski jumper

  1. Oct 6, 2009 #1
    1. The problem statement, all variables and given/known data
    After :Leaving the end of a ski ramp, a ski jumper lands downhill at a point that is displaced 51.0 m horixontally from the end of the ramp. His velocity, just before lenading, is 23.0m/s and points in a direction 43.0 degress below the horizontal. Neglecting air resistance and lift he experiences while airborne, find his initial velocity (magnitude and direction) when he left the end of the ramp. Express the direction as an angle relative to the horizontal.

    2. Relevant equations
    x = 1/2at(squared) +vot +xo

    3. The attempt at a solution
    Thinking I should use the final velocity and figure out how much the acceleration of gravity has effected it, just need some guidance there.

    Yeap you are correct you just have to resolve the velocity into the x and y component.
