Help in 2dimensions.

You're not the first person to struggle with solving 2d kinematics (projectile motion) problems.

Here are a few helpful links....

PhysicsClassroom Projectile Motion (also links to problem solving strategies)

Boston University: Motion in 2 dimensions (algebra-based)

Here are two videos showing how to solve 2-d projectile motion problems.
VIDEO #1
VIDEO #2

Projectile Motion Simulator

Launch a piano over David's head! 

pHet Simulator game will let you explore how changing angles, air resistance, mass, etc. affect the motion of a projectile.

Solving Vectors Graphically

Here are the practice problems we worked on in class.  These should be done with graph paper & protractor, but do not use Trigonometry.  Solve them GRAPHICALLY.
