An engineer, who is designing a water toy, is making preliminary calculations. A user of the product will apply a force F₁ that moves a piston (D = 80 mm) at a speed of V_piston = 300 mm/s. Water at 20°C jets out of a converging nozzle of diameter d = 15 mm. To hold the toy stationary, the user applies a force F₂ to the handle. Which force (F₁ versus F₂) is larger? Explain your answer using concepts of the momentum equation. Then calculate F₁ and F₂. Neglect friction between the piston and the walls.
