A mass
m slides down a frictionless track of radius R=0.5m. As the mass
reaches the bottom, relative to the center of curvature, its angular
velocity is most nearly:

  1. 6 rad/sec
  2. 8 rad/sec
  3. 12 rad/sec
  4. 15 rad/sec
  5. 20 rad/sec
  6. Cannot be determined



(1) The velocity near the bottom can be found using energy
