  1. Nov 9, 2008 #1
    1. The problem statement, all variables and given/known data
    A hellicopter traveling upward at 69 m/s drops a package from a height of 500 meters. To the nearest second how long does it take to hit the ground?


    2. Relevant equations
    possibly displacement??
    v= 69
    x=500
    a=9.8
    t=??


    3. The attempt at a solution
    do i use
    X=1/2 at^2 +Vt ??

    That'd work out just fine.

    Figure how high the package goes after being released and then figure how long it takes to drop the total distance and add that to the time it took to go up from 500 and that will be your total time.
