A balloon floating upward at a constant velocity.
Explanation: Constant velocity means zero acceleration, so the net force is zero (buoyant force and drag balance the weight). The other situations involve acceleration (deceleration on landing, centripetal acceleration on the circular track, and acceleration due to gravity when falling).
