A football of mass 0.450 kg is sent in the air with a speed of 16.0 m/s. It covers a distance of 30.0 m and reaches the same horizontal level as that of its initial point. If an air resistance of 0.400 N acts constantly on the football opposite to its motion during its flight, determine its final speed.
