(Figure 1)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. The airplane flies horizontally with constant speed of 462 km/hour at an altitude of 575 m. The positive x and y directions are defined in the figure. For all parts, assume that the "island" refers to the...
