Homework Help: Don't get this 2d motion problem?

  1. Oct 26, 2009 #1
    don't get this 2d motion problem??

    1. The problem statement, all variables and given/known data
    a player kicks a football at an angle of 40.0 degrees above the horizontal with an initial speed of 14.0 m/s. Air resistance may be ignored. A second player standing at a distance of 26.0m from the first(in the direction of the kick) starts running to meet the ball at the instant it is kicked. How fast must he run in order to catch the ball just before it hits the ground?

    2. Relevant equations

    3. The attempt at a solution

    i don't get the concept at how to do this when the question asks me "to catch the object before it hits the ground"

    Just assume the player catches the ball a tiny tiny amount (effectively 0 meters) above the ground.
