Xpult+Data




 * These are the four graphs that I got. In the number of rubber bands graph, I noticed that the more rubber bands you have, the further the shot will go. On my second graph, the pull back angle one, I noticed that the launch angle 45 was worse in the beginning then the 60 but better in the end. The reason of this is because the further the pull back angle is, the further the ball goes until you reach the point where the pull back angle is to far back. That is why it dropped drastically in the 60. The 45 was not to far back in the end and it shot very well. On the third chart, the launch angle graph, the end had the shot going straight up. In the beginning, the distance was about where I thought it would be. On my last graph, the waffle vs ping pong ball one, I thought the waffle would be higher. I thought it would be around the same until the end like the data shows. I thought this because the waffle is lighter then the ping pong ball, though, catches more wind. My graph had to be rounded to to the nearest 1/3, 1/2, or whole because the simulation is in inches. I did not expect the ending to be that drastic anyway. To sum up, these are my graphs on the Xpult data. **
