An airplane is flying horizontally with a constant velocity of 170 m/s at an altitude of 4500 m when it drops a package.
(a) How long does it take for the package to reach the ground?
(b) What is the distance between the airplane and the package when the package hits the ground? Ignore air resistance.
(c) How far ahead of the target along the x direction should the plane be when it releases the package?
