A jet aircraft has 6 of its identical jet engines working together. The rate at which the fuel mixture flows into each of the engines is 576 kg/s. The fluid flow velocity of the gas into the nozzle is 4.3 m/s and it leaves the nozzle at a velocity (in the same direction) of 49 m/s. Calculate the total thrust force applied to the aircraft
