Supplies are being dropped from a Chinook helicopter at a military outpost. When the copter arrives over the landing area at an altitude of 1,040 m, it descends vertically at a constant speed 28 m/s and after 15 s drops the supply package. The copter then ascends and returns to base.

1. What is the speed of the package when it hits the ground?

2. How high in the air above the ground was the package when it started to fall to the ground?

(Note: the package is still moving upwards when it is released)

3. How long did it take package to land on the ground from the time it was released?

4. From what height above the ground was the package dropped?
