Puck A, of inertia m, is attached to one end of a string of length β , 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 β/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}} = ?

Complete these sentences. if a roller coaster train has a potential energy of 1,500 j and a kinetic energy of 500 j as it starts to travel downhill, its total energy isj. once the roller coaster train gets closer to the bottom of the hill, its kinetic energy increases to 1,100 j, and its potential energy decreases to j. when the train reaches the bottom of the track and is traveling along the ground, its kinetic energy isj.
