A rocket is held stationary by the horizontal force, F(x) and the vertical force F(z) during a test run. The velocity and pressure of the exhaust gas are 5000 ft/s and 20 psia at the nozzle exit. which has a cross sectional area of 60 in^2. The exhaust mass flow rate is constant at 21 lbm/s. Assuming that the exhaust flow is approximately horizontal, determine the values of the restraining force F(x).
