(a) If the pistol is fired horizontally at a height of 1.40 m, determine the time interval (in s) required for water to travel from the nozzle to the ground. Neglect air resistance. S (b) If the desired range of the stream is 7.50 m, with what speed v₂ (in m/s) must the stream leave the nozzle? m/s (c) At what speed v₁ (in m/s) must the plunger be moved to achieve the desired range? m/s (d) What is the pressure (in Pa) at the nozzle? Pa (e) Find the pressure (in Pa) needed in the cylinder. Pa (f) Calculate the force (in N) that must be exerted on the trigger to achieve the desired range. (The force that must be exerted is due to pressure over and above atmospheric pressure. Enter the magnitude.) N
