Homework Statement

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.

You have the initial speed, the acceleration, and the distance …

so use one of the standard constant acceleration equations
