Question

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. When you quickly move the nozzle
away from the vertical, you hear the water striking the ground next to you for 2.0 s. What is the
water speed as it leaves the nozzle?
​

Answer 1

Answer:

I assume you want to know how high the stream of water reached.

Well, you have so little information, the useful formulas are necessarily few. How about

s = 1/2 at2 ?

You have a and t, so plug 'em in to get s, the height

s = 4.9 (2.2)2 = 23.716m

That's some nozzle! 7 stories high!
