1. The problem statement, all variables and given/known data A rigid, uniform bar with mass m and length b rotates about the axis passing through the midpoint of the bar perpendicular to the bar. The linear speed of the end points of the bar is v . What is the magnitude of the angular momentum of the bar? 2. Relevant equations L=Iw I=1/12(ML^(2) This L is the length. v=wr 3. The attempt at a solution L=1/12*m*B^(2)*w v=wr it says that the linear speed of the bar at the end points is v When I first read that I automatically thought that I would have to double v=wr because it has two endpoints. However, that is wrong. Why is it that I am only supposed to use a single v=wr?
