An airplane is dropping bales of hay to cattle stranded in a blizzard on the Great Plains. The pilot releases the bales at 140 m above the level ground when the plane is flying at 70.0 m/s at an angle of 50.0 ? above the horizontal. At what distance before reaching the cattle should the pilot release the hay so that the bales will land at the point where the cattle are stranded?

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 452 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...
