time in air: t=sqrt(2gh)
horizontal distance: 42*time
horizonal velocity: same as plane
vertical final: g*timeinair
An Alaskan rescue plane traveling 42 m/s drops a package of emergency rations from a height of 117 m to a stranded party of explorers.
The acceleration of gravity is 9.8 m/s2 .
Where does the package strike the ground relative to the point directly below where it was released?
