A meter stick is held vertically with one end on the floor and is then allowed to fall. Find the speed of the other end just before it hits the floor, assuming that the end on the floor does not slip. (Hint: Consider the stick to be a thin rod and use the conservation of energy principle.) In doing this problem, I do not understand what the axis of rotation is and do not understand how to use the parallel-axis theorem.
