In this project we were told to create a launcher that can launch a beanbag or ball a certain distance. Some of the constraints we had to follow included only using VEX equipment/ teacher approved materials, able to adjust to different angles, have an initial velocity, must launch at least 5 feet, and it must be consistent. Me and my partner came up with various ideas but eventually agreed to create a launcher that was similar to a balista. We considered creating a catapult, but we thought other groups would have similar designs.

Calculations and Launches
All my calculations and launches can be found in my notebook. We were able to hit the target in 2 out of the 3 launches.
Reflection
Overall, I think our machine was pretty accurate. We were able to hit 2 out of the 3 targets, and on the one we missed we weren't that far off. Compared to others in the class, we were in the middle. We did better than some groups, but also have room to improve. I think me and my partner collaborated well and were able to finish the project on time. Most of the time we were on task and were able to communicate well in order to make sure we finished everything we needed to. One thing I think we could improve on is documenting our ideas in our engineering notebook. Most of the time we just talked to each other instead of writing them down. We used simple machines in our project and did not use electricity or coding. We mostly used a first class lever to launch the beanbag. The most difficult part of the project was coming up with an idea that was consistent. Although our project was very powerful, it seemed like there were multiple places for error (accurate angle, consistent velocity, etc.)
