    where can I find them?

    all forms to find out any missing quantity?

    Welcome to Physics Forums.

    For the direction with acceleration (vertical, in the case of projectile motion), the equations are the same as the 1-D equations for constant acceleration. Just be aware that the velocity can be expressed as either vy or v·sinθ.

    For the direction without acceleration, it is motion with a constant velocity and there is really just one equation, [itex]\Delta x \ = \ v_x \ \Delta t[/itex]. An alternative form of the same equation is to express the velocity component as v·cosθ.

    Hope that helps.
