3) If an airplane is in flight cruising at constant velocity, what can be said about the net work
being done on the plane?

Draw a free-body diagram that supports your answer.

Explanation:

Yes!In physics, constant velocity occurs when there is no net force acting on the object causing it to accelerate. In terms of airplane flight, the two main forces influencing its velocity forward are drag and thrust. At a constant altitude, when the force of thrust equals the opposing force of drag, then the airplane will experience uniform motion in one direction. This can be further explained by Newton’s First Law.
