A package of medical supplies is released from a small airpllane flying a mercy mission over an isolated jungle settlement. The plane flies horizontally with a speed of 20 m/s and an altitude of 20 meters. How far from the release point will the package strike the ground?

Answer 1

IT goes down 20 meters.
Horizontal= 20m/s*timeinair

to get time in air,

20m=1/2 g t^2 or t= sqrt 2*10/9.8 sec
