While out hiking Mr. Stancek comes to a small cliff with water at the base. He decides to pick up a stone and tosses it into the water that is 10.0 m below. Mr. Stancek throws the rock horizontally with a velocity of 3.0 m/s, how far out from the edge of the cliff will it hit the water?

Please help if you can!! I am offering many points, so if you answer just for the points and not the actual answer, I WILL report you.
