Puck a, of inertia m, 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. a. how does the magnitude of the angular momentum of puck a about its pivot compare with that of puck b about its pivot? b. how does the rotational kinetic energy of a compare with that of b?
