1. The problem statement, all variables and given/known data A fountain projects water horizontaly at a height of 12 m. The water goes on the floor after having travelled 15 m horizontally. Calculate the angle the water does with the floor. 2. Relevant equations I know that the accelerate is constant, so its one of the cinematic equation. Not sure of which one. 3. The attempt at a solution I have no idea on how to do this. I know that I must decompose my situation in to two components, one for the x's and the other for the y's. Any hint would be helpful !
