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?(1 point)

The plane's net force is calculated by subtracting the wind's speed from the plane's speed. In this case, the net force would be 70 kilometers per hour - 5 kilometers per hour, which equals 65 kilometers per hour.
The plane's net force can be calculated by subtracting the force of the tailwind from the plane's original speed.
Net force = Plane's original speed - Force of tailwind
Net force = 70 km/h - 5 km/h
Net force = 65 km/h
The net force acting on the plane can be calculated using the following formula:
Net Force = Mass x Acceleration
However, in this scenario, we are given the speed of the plane, not the acceleration. To calculate the acceleration, we can use the formula:
Acceleration = Change in Velocity / Time
The change in velocity is equal to the initial speed of the plane (70 km/h) plus the speed of the tailwind (5 km/h), as they are moving in the same direction. So the change in velocity is 70 km/h + 5 km/h = 75 km/h.
Assuming the time is constant, the acceleration will be 75 km/h divided by the time.
Now, let's assume that the mass of the plane is unknown. In that case, we cannot calculate the net force as we require both mass and acceleration.
