a uniform 172 g meter stick rotates about an axis perpendicular to the stick passing through its center with an angular speed of 6.25 rad/s. (a) What is the magnitude of the angular momentum of the stick? (b) What would be the angular speed of the meter stick if it is rotated with the same angular momentum as in part (a) but about an axis of rotation situated at one end of the meter stick and parallel to the axis in part (a)? (You do not need the correct angular momentum for part (a) to get the correct answer to part (b))
