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 483 km/hour at an altitude of 825 m . The positive x and y directions are defined in the figure. For all parts, assume that the "island" refers to the...

A plane is dropping supplies to a raft adrift on the ocean. Just before the plane drops the package, it dives at an angle of 25 degrees (relative to the horizontal). The package's inital velocity is also declined by 25 degrees. The plane is at an altitude of h=300m and if flying at a constant speed of v=90m/s when the package is dropped. There is a strong current that is pushing the raft at a constant rate with v_raft =...

A rescue plane flies horizontally at a constant speed searching for a disabled boat. When the plane is directly above the boat, the boat's crew blows a loud horn. By the time the plane's sound detector receives the horn's sound, the plane has traveled a distance equal to one-fourth its altitude above the ocean. Assuming it takes the sound 2.16 s to reach the plane, and taking the speed of sound to be 343 m/s, determine the following. (a) the...
