1. The problem statement, all variables and given/known data A helicopter is ascending vertically with a speed of 5.10 m/s. At a height of 115m above the Earth, a package is dropped from a window. How much time does it take for the package to reach the ground? [Hint: v_0 for the package equals the speed of the helicopter.] 2. Relevant equations x=x_0 + v_0t+ (1/2)at^2 3. The attempt at a solution I have no idea.
