Trajectory

Overview
"In this event you must make a device that is able to launch a pliable, hollow ball that is 3cm to 9cm. Your device must be powered by a non metallic elastic soild. The device you make must fit in an 80cm by 80cm cube. The launch area in which you place your device is a 1m by 1.5 m rectangle. You want the ball to hit a target between 2 and 8 meters. There are two targets at least 2 meters apart. Each target is either a 1m by 1m square or a 1m diameter circle. At the Regional level, targets are placed at 1 meter intervals. At the State level, targets are placed at 1/2 meter intervals. At the National level, targets are placed at 10 cm intervals. You must tell the judges which target you are going to try to hit and when you are going to fire. One of the targets is on the ground and the other one is up to one meter off of the ground, at 10 cm intervals. The goal is to be able to hit both targets and be accurate. When scoring, you want to get the least amount of points. Four graphs and tables must also be turned in, worth 100 points each. Your target score is the number of millimeters from the center of each target. Penalties are also given for not wearing safety goggles, being inside launch area during launch, the part of the device being outside of the 80cm x 80cm x 80cm cube before or after launch, and the device being outside of launch area. A 100 point penalty is added when any of those occurs."
