projectile motion?????

There is quite a bit to projectile motion. It is a form of two (or three) dimensional motion, and all the kinematics equations you used for1-dimensional motion, applies to projectile motion as well.

Remember that you'll need to find the horizontal and vertical components of the velocity for the projectile. If the angle is measured (say above the horizontal, positive x axis) then the horizontal initial velocity component would be v?cos? and the vertical component would be v?sin?. If the initial and final vertical positions of the projectile are different (i.e., the projectile lands higher or lower than it was launched from), then this difference is ?y.

Keep in mind too, that the velocity horizontally (neglecting air resistance and other forces) remains constant.because it is non accelerated (gravity does not act horizontally).

Hope this helps.
