I need help figuring out how to work out this problem. Step-by-step is very helpful

(See Fluids in the News article titled "Where the plume goes".) Air flows into the jet engine shown in the figure below at a rate of 9
slugs/s and a speed V₁ of 349 ft/s. Upon landing, the engine exhaust exits through the reverse thrust mechanism with a speed V₂ = V3 of
806 ft/s in the direction indicated. Determine the reverse thrust applied by the engine to the airplane. Assume that the inlet and exit
pressures are atmospheric and that the mass flowrate of fuel is negligible compared to the air flowrate through the engine.
