Question C

In a water pistol, a piston drives water through a larger tube of area A1 into a smaller tube of area A2 as shown in the figure
below. The radius of the large tube is 1.40 cm and that of the small tube is 1.10 mm. The smaller tube is 3.00 cm above the
larger tube.
A2
A
(a) If the pistol is fired horizontally at a height of 1.60 m, determine the time interval required for water to travel from
the nozzle to the ground. Neglect air resistance and assume atmospheric pressure is 1.00 atm.
.58
(b) If the desired range of the stream is 7.50 m, with what speed 2 must the stream leave the nozzle?
12.9
m/s
(c) At what speed v1 must the plunger be moved to achieve the desired range?
m/s
