- 5. Multiple ChoiceIf a bullet is horizontally shot at the same moment another bullet is dropped from the same height, which will hit the ground first?(neglect air resistance)Shot BulletDropped BulletHit at Same Time
- 6. Multiple ChoiceIf you shoot a gun and at the same time drop a bullet which will hit the ground first? Why?The bullet that is shot, because it is going fasterThe dropped bullet, because gravity pulls on it.At the same time, because the x and y components are independent of each other.This cannot happen
