Question:

A fire hose held near the ground shoots water at a speed of 6.7 m/s

At what angles should the nozzle point in order that the water land 20.m away?Small angle and largeIve tried this so many times I am struggling a bit with projectile motion but I am getting there HELP on this one though

Answer:

Mantis shrimp generally reek havoc on reef tanks. They can even break the tank. Now I'm not sure about crushers, I thought they all were dangerous to you, and to all the life in the tank. Thumb splitters they call them.
I love them and i have one. I like both the studs and the one that hang down. (:
