I have the Giancoli text and I ran across this lvl III problem (pg 44 , #48) on the hmwk:
Suppose you adjust your garden hose nozzle for a hard stream of water. You point the nozzile vertically upwatd at a height of 1.5 m above the graound. When you quickly move the nozzle away from the vertical, you hear the water striking the ground next to you for another 2.0 secs. What is the speed as it leaves the nozzle
the drawing is something like this. The hose is the dash, the water is the x, the side dash is the length above the ground:
then it comes curving down in a parabola, the hose is 1.5 m from the ground

- sorry for the bad illustration. I can't get it to work right
- I got 4.2 m/s after a bunch of algebra, can someone tell me if that's right and work it out possibly?
