A package is dropped from an airplane travelling horizontally at constant speed. Friction is negligible. One second later a second package is dropped. What will happen to the distance between the two packages as they fall?
1) The distance between the two packages will remain constant as they fall
2) The distance between the two packages will steadily increase as they fall
3) The second package will hit the ground more than one second after the first hits
4) The horizontal distance between the two packages will decrease as they fall
