Oh I get it now! I was really confused for a sec, but it makes sense. Thank TSny!

Sorry about the formulas...I'm still working on the latex thing.

Well I am a beginning physics student, so the following may not be correct. Since this is a velocity versus time graph, the slope is going to give you acceleration. That means you know initial velocity, final velocity, time, and acceleration. If I were solving this, I would plug that information...

Time is given in the problem as 3.00s. The speed of sound is minimal, and not much use until I know how far the rock actually traveled. How can I use this time to find the x-displacement and/or inital velocity in the x direction?

Homework Statement A soccer player kicks a rock horizontally off a 40.0m-high cliff into a pool of water. If the player hear the sound of the splash 3.00s later, what was the initial speed given to the rock? Assume the speed of sound in air to be 343 m/s. I wrote down givens in the...
