Consider a missile, which is flying in a general direction under its own power. If we break the acceleration of this missile into two components, in the vertical and horizontal direction, what statement correctly characterizes the source of the acceleration? The horizontal acceleration is due only to the thrust from the missile, whereas the vertical acceleration is only due to gravity. Both the vertical and the horizontal accelerations depend on the thrust force and gravity. Both the vertical and the horizontal accelerations are due solely to the thrust from the missile. The horizontal acceleration is due only to the thrust from the missile, whereas the vertical acceleration is due to both the thrust and gravity
