What Are the Equations for Projectile Motion?

[weikari]

Homework Statement

A firefighter, 50.0 m away from a burning building, directs a stream of water from a fire hose at an angle of 40.0° above the horizontal, as in figure. If the speed of the stream is 30.0 m/s, at what height will the stream of water strike the building?

The Attempt at a Solution

Im really not sure how to answer the problem. I know that you are supposed to integrate the height into equation. But our teacher didn't appropriately give us the needed materials.
