A helicopter drops a relief package to some isolated refugees. The package travels 250 meters forward while taking 4 seconds to land after it is released.

6. How high was the helicopter flying when it released the package?

7. How fast was the helicopter flying when it released the package?

8. How fast was the package falling vertically just before it landed on the island?

9. What was the package's impact speed, resultant velocity, when it landed on the island?

10. At what angle was the package's trajectory with respect to the ground at the instant that it landed?

11. If the helicopter pilot does not change his velocity after releasing the package, what will be the position of the helicopter when the package lands?
