1. The problem statement, all variables and given/known data I am working on a lab i did. In the lab we tracked the motion of two pucks that collided. One puck collided into another stationary puck of equal mass in an inelastic collision. We used a video capture system to record the velocity of the pucks before and after collisions as well as the rotation of the two objects stuck together. The two objects are both like hockey pucks in shape and have equal mass and radius. 2. Relevant equations I am unsure how to solve for the moment of inertia ( I ) after both pucks have stuck together.
