Watch James Bond try out this hamless centifuge. When the villain tuns it up to the highestsetting (shown), determine how many g's bond is expeiencing. Do this by estimating the time for a single period from the video. One g is 10 m/s^2. People tend to pass out at 5 g's and 10 g's is fatal velocity quickly.

A design for the world's largest roller coaster is proposed as shown. If the hill is 500m tall estimate the acceleration of the passengers at the top of the first loop (you can estimate the radius of the loop if the hill is 500m). Discuss whether you think the designer was attempting to maximize entetainment or perhaps he had a more sinister motive.
