More 2D Motion

Using things in the room, create a demonstration (or think of an everyday example from real life) of 2-Dimensional motion where
1. there is a component of acceleration parallel to the motion of the object
2. a component of acceleration perpendicular to the motion of the object
3. both

Draw a sketch of your demonstration on the board and show the acceleration vectors a_|| and a_perp at several key points during the motion. Have each person in your group be prepared to explain your demonstration.
