A rocket has a mass of 1.25 x 106 kg including fuel. Determine the constant rate at which the fuel must be burned so that its thrust gives the rocket a speed of 135 m/s in 8 s starting from rest with a vertical trajectory. The fuel exhausts from the rocket at a relative speed of 2750 m/s. Neglect air resistance and assume g is constant.
m? = _____________ FThrust = _____________
