Set up the lab as shown in class and record your data in tables that make sense to you. You should first record data for one marble (Single) rolling down the ramp without collision. Then you'll record a collision between two marbles (Stationary & Moving). For each situation, perform several trials (at least five). The marks on your page will cluster around an average. Determine the Ad (including direction) for each dot, and then calculate the average for each cluster. Remember to use the pendulum hanging from the string to mark the location of the collision on your paper Then draw lines from the spot of the collision to each of your clusters. These lines measure the horizontal distance each marble traveled while in the air
