A plane is flying horizontally at a speed of 290m/s. He drops a package (ignoring air resistance).
A)If it take 15s for the package to hit the ground, how high above is the plane?
B) How far (horizontally) before the island should Steven drop the package?
C) Assuming the airplane does not change speed or elevation, where is the airplane when the package hits the ground?
(If you can't answer these questions just give the equations for I can ATTEMPT them.. Thank you)

A. h = 0.5g*t^2 = 4.9*15^2 = 1103 m.
B. d = 290m/s * 15s = 4350 m.
C. Over the island.
