1. The problem statement, all variables and given/known data A thin bar of length L and mass M, and a small blob of putty of mass m. The system is supported on a frictionless horizontal surface. The putty moves to the right with velocity v, strikes the bar at a distance d from the center of the bar, and sticks to the bar at the point of contact. Obtain expressions for the velocity of the system's center of mass and for the angular velocity of the system about its center of mass. 2. Relevant equations L=I*omega and P=mv 3. The attempt at a solution So since the question *** for the velocity of the center of mass, I think I need to find the moment of inertia by parallel axis theorem right ?? so I= Icom + Mh^2 so Icom=(1/12)ML^2 Thus, I= (1/12)ML^2 + (M+m)*d^2. Am I right so far ? Do I need to find the center of mass ?
