Q. How might a magician make the Statue of Liberty disappear? Imagine that you are sitting with some spectators on a circular platform that, unknown to all of you, can rotate very slowly. It is evening, and you can see the Statue of Liberty a short distance away between two tall brightly lit columns at the rim of the platform. A large curtain can be drawn between the columns to temporarily hide the statue. The magician closes curtain, and then rotates the platform through an angle of just 0.171 radians so the statue is hidden behind one of the columns when the curtain is opened. (a) If platform rotation takes 24.0 seconds, what is the average angular speed required? (b) You are sitting 4.00m from the center of rotation while the platform is rotating. What is the centripetal acceleration required to move you along the circular arc? (c) Estimate the centripetal acceleration as a fraction of g. You might be unaware of the rotation, especially if you were distracted.
