1. The problem statement, all variables and given/known data On a frictionless table, a 0.50 kg glob of clay strikes a uniform 1.58 kg bar perpendicularly at a point 0.38 m from the center of the bar and sticks to it. If the bar is 1.30 m long and the clay is moving at 6.60 m/s before striking the bar, what is the final speed of the center of mass? At what angular speed does the bar/clay system rotate about its center of mass after the impact? 2. Relevant equations xcm = Ʃmixi / Mtotal ω = v/r 3. The attempt at a solution I was able to find the speed of the center of mass, which was 1.587 m/s. I also found ω for both the clay and the bar, where r = 0.289 m. For the clay it's 22.84 rad/s, and for the bar it's 72.53 rad/s. I just don't know how to relate them into one "bar/clay system". Adding, subtracting, dividing, and averaging didn't work, and I know there's something bigger I'm missing.
