84. •Medical In a laboratory test of tolerance for high angular acceleration, pilots were swung in a circle 13.4 m in diameter. It was found that they blacked out when they were spun at 30.6 rpm (rev/min). (a) At what acceleration (in SI units and in multiples of g) did the pilots black out? (b) If you want to decrease the acceleration by 25.0% without changing the diameter of the circle, by what percent must you change the time for the pilot to make one spin?
