A relief airplane is delivering a food package to a group of people stranded on a very small island. The island is too small for the plane to land on and the only way to deliver the package is by dropping it so that the package lands on a site close to the people. The airplane flies horizontally at a constant altitude 500m directly over the island and the dropped package successfully lands on the site.
1) What is the velocity of the plane if the pilot successfully drops the package from a horizontal distance, D, equal to 600 m from the site.
2) Find the magnitude and direction of the velocity of the package when it lands on the site.
