In a laboratory test of tolerance for high acceleration, a pilot is swung in a circle 12.0 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? acceleration: 61.61 m/s² Express this acceleration in terms of a multiple of g. acceleration as a multiple of g 6.28 8 If you want to decrease the acceleration by 11.0% without changing the diameter of the circle, by what percent must you change the time for the pilot to make one circle? 9.7 percent of time change: Incorrect %
