The Hydra 70 rocket is a weapon derived from the 70 mm (2.75 inch) Mk 4/Mk 40 Folding-Fin Aerial Rocket developed by the United States Navy for use as a free-flight aerial rocket in the late 1940s. The rocket uses the Mk 66 universal motor, which has a mass of 6.2 kg. The burn time of the motor is 1.07 s. The velocity of the exhaust from the nozzle is about 1030 m/s. Assuming that the burn rate is uniform. Calculate the thrust of the rocket motor.
