Question

A helicopter is accelerating up into the air while it is also accelerating due north. Which statement about the forces acting on the helicopter is true?(1 point) Responses The drag on the helicopter is directed upward and to the north. The drag on the helicopter is directed upward and to the north. The drag on the helicopter is directed downward and to the south. The drag on the helicopter is directed downward and to the south. The drag on the helicopter is directed downward and to the north. The drag on the helicopter is directed downward and to the north. The drag on the helicopter is directed upward and to the south.

Answer 1

To determine the direction of the drag force acting on the helicopter, we need to consider the basic principles of aerodynamics.

1. Acceleration Upwards: The helicopter is accelerating upwards, which means there must be a net force acting upward (greater than the combined weight of the helicopter and drag).

2. Acceleration Northwards: The helicopter is also accelerating north, which means there must be a net force acting in the northern direction as well.

3. Drag Force: The drag force (air resistance) opposes the direction of velocity motion of the helicopter. If the helicopter is moving upward and to the north, the drag will act in the direction opposite to these motions.

Thus, since the helicopter is moving and accelerating upwards and northwards, the drag force will be directed downward and to the south.

The correct statement about the drag on the helicopter is: The drag on the helicopter is directed downward and to the south.
