1. The problem statement, all variables and given/known data 1.A solid, vertical cylinder of mass 10.0 kg and radius 1.00 m rotates with an angular speed of 7.00 rad/s about a fixed vertical axis through its center. A .250 kg piece of putty is dropped vertically onto the cylinder at a point 0.900 m from the center of ration and sticks to the cylinder. Determine the final angular speed of the system. 2. Relevant equations Lbefore=Lafter L=Iw 3. The attempt at a solution the angular momentum is L and the angular velocity is what i am looking for that is w. I beleive you can say that IoWo should = IW I am unsure what you are to do with the mass of the putty and the center of radian issue. I believe you need to set up taht W = (Io/I)wo Io = MR^2???
