An army plane wants to drop supplies to a group of physics students stranded on an island. In order for the package to land on the island, the pilot needs to drop the package before the plane is directly above the island. Explain why using Newton's Laws (you may ignore air resistance).
Ans.
Newton's 1st law illustrates why the package will continue at a constant velocity in the x-direction
