Tasked with launching a ball as far as possible using LEGO, me and two other group members decided to build a catapult. We used rubber bands to store potential energy, and attached them to the bottom part of the catapult arm and the base. This provided enough energy to launch the ball 21 feet, with a launch velocity of around 18.4 mph. My role in the team was to continuously strengthen the structure of the catapult to prevent it from breaking as we added more rubber bands. Overall it was a fun first project to the year.

What I learned: How to estimate initial velocity and use Vernier video analysis software
