1. How is the KM system at NASA different from other KM systems that you have studied within the chapter? How is it similar? 2. What steps can NASA take to make sure that the KM system is better utilized by individuals and teams? 3. What can NASA do to ensure that individuals and teams can find what they need within the mountain of data residing within the KM system? 4. Is NASA’s KM system, as it exists now, a good way to combat the type of failures the agency has experienced in the past? If not, how could the KM system be changed to support mission success? 5. Are there other measures that NASA should take in addition to or in conjunction with the development of its KM system?

The center of a long frictionless rod is pivoted at the origin, and the rod is forced to rotate in a vertical plane with constant angular velocity \omega. write down the lagrangian for a bead of mass m threaded on the rod, using r as your generalized coordinate, where r, \phi are the polar coordinates of the bead. (notice that \phi is not an independent variable since it is fixed by the rotation of the rod tobe \phi = \omega * t) solve lagrange's equation for r(t). what happens if the bead is initially at rest at the origin? if it is released from any point ro > 0, show that r(t) eventually grows exponentially. explain your results in terms of the centrifugal force m* \omega ^2 *r.
