A plane dives at 31⁰ to the horizontal and releases a package at an altitude of 200 m. If the load is in the air for 4.00 s, find: (a) the speed of the plane; (b) the horizontal distance traveled by the package after it is released.
Homework Answers
Let 
be the speed of the plane.
Given time of flight, 
Given launch height, 
Vertical component of launch velocity, 
Horizontal component of launch velocity, 
Consider the vertical motion of the package
Use formula 
(a) ANSWER :
=========================
(b) the horizontal distance traveled by the package after it is released.
Consider the horizontal motion of the package
There is no acceleration in horizontal direction, so horizontal velocity remains constant.
Horizontal velocity = Horizontal distance/Time of flight

(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...
