Homework Help: Trajectory problem

  1. Feb 7, 2008 #1
    1. The problem statement, all variables and given/known data

    2 football players are 16m apart. The receiver runs perpendicular to the line joining the two palyers at a constant speed of 7 m/s. after 2 seconds the quarterbak throws the ball with a horizontal velocity of 24m/s

    In what horizontal direction and with what vertical launch should the quarterback throw the ball so it reaches the same spot that the receiver will be and what time will the ball be caught?

    2. Relevant equations

    once i get the horizontal direction I know how to determine the launch angle and time, I am not sure what to do with the first part

    3. The attempt at a solution

    I am having trouble setting up the triangle,
