1. The problem statement, all variables and given/known data What is the angular momentum of the 1.2kg, 3.6cm diameter rotating disk in the figure below? http://i241.photobucket.com/albums/ff4/alg5045/ex13-47.gif 2. Relevant equations 3. The attempt at a solution I tried using L = Iw. w = 600 rev/min x (1 min/60s) x 2*pi radians = 62.832. Then I found I = 1/2 m(r^2) = .019. Then L = 1.194, but it wasn't right.
