Physics
A helicopter is ascending vertically with a speed of 3.00 m/s. At a height of 70 m above the Earth, a package is dropped from a window. How much time (in seconds) does it take for the package to reach the ground? [Hint: The package's initial speed equals the helicopter's.]

physics
The height of a helicopter above the ground is given by h = 3.40t^3 , where h is in meters and t is in seconds. After 2.05 s, the helicopter releases a small mailbag. How long after its release does the mailbag reach the ground?
