Finding Initial Velocity in 2D Kinematics Problems

Homework Statement

Water from a garden hose that is pointed 25 degrees above the horizontallands directly on a sunbather lying on the ground 4.4 m away in the horizontal direction. If the hose is held 1.4 m above the ground, at what speed does ithe water leave the nozzle?

Homework Equations

The Attempt at a Solution

I am utterly clueless, however suspicious it may seem. It's summer homework, and textbooks were not designed to be used without the aid of a teacher. I'd prefer some general advice on how to do problems like this, where you are given the angle measure and displacement and must find v_0. However, I decided using the template best I could would be a good idea.

Try to write out the equations for vertical displacement and horizontal displacement. Think of it as a simple projectile (a rock or something)... instead of water...

well, your advice helped me solve a similar, easier problem. thanks. I got as far as I could on this one, but I've actually got to go turn this in at the school. I'll just have to take the penalty and try to figure this one out before our first-week-of-school test.
