The drag force acting on the helicopter is always opposite to the direction of its velocity. Since the helicopter is moving upward (accelerating up) and to the north (accelerating north), the drag force would be directed opposite to that motion.
Here are the correct directions for the drag force based on the helicopter's motion:
- Upward motion (against gravity): Drag force would act downward.
- Northward motion: Drag force would act to the south.
Therefore, the correct answer is:
The drag on the helicopter is directed downward and to the south.
