As a small aircraft approaches a landing strip, it is flying along horizontally at constant (low) altitude. The air speed (relative to the plane) over the top of the wings is 62.0 m/s, whereas the air speed beneath the wings is 54.0 m/s. The total effective wing area (including both wings) is 16.0 m2. What is the weight of the plane? Air density = 1.29 kg m-3.
