To determine the direction of the drag force on a helicopter that is accelerating upwards and to the north, we need to consider the nature of drag force.
The drag force acts in the opposite direction to the motion of the object through a fluid. Since the helicopter is moving upwards, the drag force will act downward. Additionally, since it is accelerating to the north, the drag also acts opposite to that direction.
Therefore, the drag force on the helicopter is directed downward and to the south.
The correct response is: The drag on the helicopter is directed downward and to the south.
