Festinger Group TitleBest ResponseYou've already chosen the best response.1
You can either refer to newton's first or second law. There is no net force in the xdrection, and hence no acceleration in that direction.

dw:1380322334732:dw With projectile motion, we often choose the y direction to be verticalthis is the direction in which gravity acts! We often choose the x direction as horizontal. The kind of math we use in Physics allows us to say that the x and y directions (which are perpendicular to each other) exist separately. SO the influence of gravity, which works in the y direction, does NOT effect the x direction. There is no acceleration due to gravity in the x direction. What else could case an acceleration in the x direction? Well, air resistance could, but we often IGNORE air resistance. SOthere is NO ACCELERATION IN THE X DIRECTION! Also, as Festinger wrote, you can consider FORCES, which we usually learn about after we learn about basics of motion.

In a projectile there is only one acceleration.. that is of the gravity The gravity is in the Yaxis ...So there is no acceleration along Xaxis... If u like to have an acceleration in the Xaxis u can change the Coordinate system ;) :D
