Margaret Thatcher wants more blue in the Canadian flag to make it appear more British. So, she glues Peaheir TrueDough to the centre of his transparent red bar, of length 2L, and illuminates the red bar with two Blue Light Bars on either side that are parallel to it, as shown. Then she puts on her magical Wizard costume and hovers in one position, as shown, and magically causes the red bar and blue light bars to rotate together in a clockwise direction at constant speed about an axis of rotation such that the fastest points on the bar have a speed of vo. While rotating with the red bar, the Blue Light (not to be confused with the beer) shines straight toward the transparent red bar causing the shadow of the Wizard to move along the red bar towards and away from Peaheir who can even see the Wizard's shadow through the transparent red bar when the Wizard is on the other side. At some point the Wizard's shadow is moving away from Peaheir at a distance L in front of him. Then, 1.2 s later, the shadow is in front of Peaheir moving towards him at a speed of vo. How much time, in seconds, does it take Peaheir to complete a full cycle? This Blue Light Bar makes light shine perpendicular to the red bar Hovering Wizard Peaheir TrueDough L.
