Long Jump Question - Net forces

  1. Feb 23, 2009 #1
    1. The problem statement, all variables and given/known data
    A Long-Jump Contestant experiences at the instant of landing, a gravitational force of 538N [Downwards], and a force applied by the ground to the feet, of 6382N [28.3 degrees above the horizontal]

    (The answer is given in the book, being 6.15 X 10^3 N [23.9 Degrees above the Horizontal]
    I just can't find out how to get there.
    I have no idea on how to start this equation.
