Use conservation of energy to determine the angular speed of the spool shown in the figure below afterthe 3.00kg bucket has fallen 4.05 rn, starting from rest. The light string attached to the bucket is wrapped around the spool and does not slip as it unwinds. x Your response differs from the correct answer by more than 10%. Double check your calculations. rad/'5 (a) Calculate the angular momentum of Earth that arises from its spinning motion on its axis, treating Earth as a uniform solid sphere. (b) Calculate the angular momentum of Earth that arises from its orbital motion about the Sun, treating Earth as a point particle
