In a laboratory test of tolerance for high acceleration, a pilot is swung in a circle 11.5 m in diameter. It is found that the pilot blacks out when he is spun at 30.6 rpm (rev/min). At what acceleration (in SI units) does the pilot black out? Express this acceleration in terms of a multiple of g. If you want to decrease the acceleration by 13.0% without changing the diameter of the circle, by what percent must you change the time for the pilot to make one circle? acceleration: acceleration as a multiple of g: percent of time change: m/s² %
