Homework Help: One Dimension Free-Fall Problem

  1. Oct 4, 2005 #1
    5. Sue is watching Hugh 7.2 meters below her when she sees him throw a ball up to hit her. She pulls in her head, but Hugh purposely threw the ball hard enough to hit her on his way down 1 second after it passes her on the way up. Explain how hugh figured this out...

    I used a sort of system of equations...but it is comin out to 16.66 as the Vo, but when i plug it into the equation, it doesnt fit the other times
