Solving for Motion in 2-D Remember, vectors can be broken into components! 2-D can just be solved as 2 independent problems in one dimension! Perpendicular directions must be chosen to do this!
Once again . . . Constant Acceleration! What Equations can we use to solve problems with constant acceleration? Constant Acceleration in the vertical direction (ie. Gravity) and no acceleration in the horizontal direction is given a special name . . . The Kinematic Equations Projectile Motion!
