After a package is dropped from the plane, how long will it take for it to reach sea level from the time it is dropped? Assume that the package, like the plane, has an initial velocity of 382 km/hour in the horizontal direction. Express your answer numerically in seconds. Neglect air resistance. Item 10 10 of 13 Submit Request Answer Part B If the package is to land right on the island, at what horizontal distance D from the plane to the island should the package be released?

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 382 km/hour at an altitude of 775 m. The positive x and y directions are defined in the figure. For all parts, assume that the "island" refers to the point at a distance D from the point at which the package is released, as shown in the figure. Ignore the height of this point above sea level. Assume that the acceleration due to gravity is g = 9.80 m/s? . After a package is dropped from the plane, how long will it take for it to reach sea level from the time it is dropped?
