1. The problem statement, all variables and given/known data A projectile of mass m = 1.49 kg moves to the right with speed v0 = 19.6 m/s. The pro- jectile strikes and sticks to the end of a sta- tionary rod of mass M = 6.55 kg and length d = 2.29 m that is pivoted about a frictionless axle through its center. Find the angular speed of the system right after the collision. Answer in units of rad/s. 2. Relevant equations Icom rod = (1/12)ML^2 3. The attempt at a solution[/b I figured I would use conservation of angular momentum to determine the final angular speed. I'm unsure how to find the initial angular momentum. I can find the final moment of inertia. (1/12)(1.49 + 6.55)(2.29)^2 = 3.51 HELP!
