Need help combining various equations for a single problem

  1. Feb 4, 2012 #1
    1. The problem statement, all variables and given/known data
    A helicopter is ascending vertically with the speed of 5.20 m/s. At a height of 125 m above the Earth , a package is dropped from a window. How much time does it take for the package to reach the ground.
    I am brand new to physics , but to me it seems like there is not enough info here . I know that there probably is I just don't know where to start.



    2. Relevant equations g= 9.80 m/s2



    3. The attempt at a solution

    Welcome to PF!

    Hi ZPoston! Welcome to PF! :wink:
    You have the initial speed, the acceleration, and the distance …

    so use one of the standard constant acceleration equations :smile:
