What is Kleppner: Definition and 52 Discussions

Daniel Kleppner, born 1932, is the Lester Wolfe Professor Emeritus of Physics at MIT and co-director of the MIT-Harvard Center for Ultracold Atoms. His areas of science include Atomic, Molecular, and Optical Physics, and his research interests include Experimental Atomic Physics, Laser Spectroscopy, and High Precision Measurements. He is the winner of the 2005 Wolf Prize in Physics, the 2007 Frederic Ives Medal, and the 2014 Benjamin Franklin Medal. Prof. Kleppner has also been awarded the National Medal of Science (2006). In 2007 he was elected to the American Philosophical Society. Together with Robert J. Kolenkow, he authored a popular introductory mechanics textbook for advanced students. Kleppner graduated from Williams College with a B.A. in 1953, Cambridge University with a B.A. in 1955, and Harvard University with a Ph.D. in 1959.

    Pulling down on the string connected to a whirling block on a table

    At the time of release, the equation of motion of blocks A and B T-m_ag = m_aa and T=m_b\omega^2R respectively, where T is the tension in the string. Solving for the acceleration a then gives a=\frac{m_b\omega^2R - m_ag}{m_a}. Not sure what I did wrong or what incorrect assumptions I made...
