(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

An airplane flying 914 m above the ocean at 116 km/hr is supposed to drop a box of emergency supplies to the survivors of a shipwreck on an island. At what final speed will the supplies land on the island?

2. Relevant equations

3. The attempt at a solution

So Vx = 32.222 m/s, is Voy = 0 m/s?

a = -9.8 m/s/s and y = -914 m?

So I did Vfy^2 = Voy^2 +2ay and got -133.845 m/s, but that is not right...
