Suppose you adjust your garden hose nozzle for a hard
stream of water. You point the nozzle vertically upward at a
height of 1.5 m above the ground (Fig. 2-45). When you
quickly turn off the nozzle, you
hear the water striking the
ground next to you for another
2.0 s. What is the water speed
as it leaves the nozzle?
