The figure below depicts a camshaft assembly such as one that might be found in an automobile engine to open and close intake and exhaust valves. The cam is a circular disk of radius R with a hole of diameter R cut through it. As shown in the figure, the hole does not pass through the center of the disk. The cam with the hole cut out has mass M. The cam is mounted on a uniform, solid, cylindrical shaft of diameter R and also of mass M. What is the kinetic energy of the entire camshaft assembly when it is rotating with angular speed w about the shaft's axis? (Use any variable or symbol stated above as necessary.) -2R K =
