1. The problem statement, all variables and given/known data A helicopter is ascending vertically with a speed of 5.83 m/s. At a height of 121 m above the Earth, a package is dropped from a window. How much time does it take for the package to reach the ground? 2. Relevant equations Vfinal=Vinitial + at or Xfinal=Xinitial + Vinitial(t) + (1/2at)squared 3. The attempt at a solution I tried putting in my answer from the first equation but it was wrong, and every time I try the second equation I get a negative answer which doesn't make sense.
