$($a$)$ If the pistol is fired horizontally at a height of $1\mathrm{.}40$ m $,$ determine the time interval $($in s$)$ required for water to travel from the nozzle to the ground. Neglect air resistance.

$($b$)$ If the desired range of the stream is $7\mathrm{.}80$ m $,$ with what speed $v_2($in $\frac{m}{s})$ must the stream leave the nozzle?

$$

$\frac{m}{s}$

$($c$)$ At what speed $v_1($in $\frac{m}{s})$ must the plunger be moved to achieve the desired range?

$$

$\frac{m}{s}$

$($d$)$ What is the pressure $($in Pa $)$ at the nozzle?

$$

$Pa$

$($e$)$ Find the pressure $($in Pa $)$ needed in the cylinder.
