(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Suppose you adjust your garden hose nozzle for a hard stream of water. You point the nozzle vertically upward at a height of 1.5m above the ground. When you quickly move the nozzle away from the vertical, you hear the water striking the ground next to you for another 2.0 seconds. What is the water speed as it leaves the nozzle?

2. Relevant equations

I'm assuming you have to use the formula

x(t)=height + Vo * t - 1/2 * a * [tex]t^2[/tex]

3. The attempt at a solution

So I plugged in the values given, and came up with this.

x(t)=1.5 + v(2) -1/2 * 10 * [tex]2^2[/tex]

x(t)=1.5 + v(2) - 20

Now I'm kind of stuck though. It seems to me I have two variables, and nothing to do with them. Any help would be greatly appreciated.
