A plane is flying at a speed of 70 kilometers per hour. Then a tailwind (moving in the same direction as the plane) of 5 kilometers per hour acts on the plane. How is the plane’s net force calculated?

Divide the larger force by the smaller force

Multiply the two forces

Subtract the smaller force from the greater one

Add the two forces together

Add the two forces together.

To calculate the plane's net force, you need to subtract the smaller force from the greater one. In this case, the force of the tailwind is the smaller force, while the force from the plane's speed is the greater force. So, you would subtract the force of the tailwind (5 kilometers per hour) from the force of the plane's speed (70 kilometers per hour).

To calculate the net force acting on the plane, you need to add the forces together. In this case, the plane is flying at a speed of 70 kilometers per hour, and there is a tailwind of 5 kilometers per hour. Since the tailwind is moving in the same direction as the plane, it will contribute to the plane's speed.

To calculate the net force, you add the speed of the plane to the speed of the tailwind. In this case, it will be:

70 km/h (plane's speed) + 5 km/h (tailwind's speed) = 75 km/h (net force)

So the correct answer is to "Add the two forces together."
