Problem
A rescue worker standing at the edge of a cliff that is 25 m above a river must throw a 1.0 kg rope bundle horizontally so it lands 18 m away at the position of a stranded kayaker. Air resistance is negligible.
Determine the minimum horizontal launch speed the worker must give the bundle. Use g=9.8m/s2.
