Puck A, of inertia m, is attached to one end of a string of length ℓ , and the other end of the string is attached to a pivot so that the puck is free to revolve on a smooth horizontal surface. Puck B, of inertia 8m, is attached to one end of a string of length ℓ/2, and the other end of the string is attached to a second pivot so that B is also free to revolve. In each case, the puck is held as far as possible from the pivot so that the string is taut and then given an initial velocity v perpendicular to the string. Part AHow does the magnitude of the angular momentum of puck A about its pivot compare with that of puck B about its pivot?\frac{L_{\theta ,B}}{L_{\theta ,A}} = ?Part BHow does the rotational kinetic energy of A compare with that of B?\frac{K_{rot ,B}}{K_{rot ,A}} = ?
