Question
What is the net force on an 800-kg airplane flying with a constant velocity of 160 km/hournorth?
Solution
The net force on an object moving at a constant velocity is zero. This is due to Newton's first law of motion, which states that an object in motion will stay in motion with the same speed and direction unless acted upon by an unbalanced force. In this case, the airplane is moving at a constant velocity, which means the forces acting on it (gravity, lift from the wings, thrust from the engines, and air resistance) are balanced. Therefore, the net force is zero.
