In a laboratory test of tolerance for high acceleration, a pilot is swung in a circle 15.0 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: 77.01 m/s? Express this acceleration in terms of a multiple of g. acceleration as a multiple of g: 7.858 If you want to decrease the acceleration by 22.0% without changing the diameter of the circle, by what percent must you change the time for the pilot to make one circle? percent of time change:

(b) Show that we can write the acceleration as a = arT + anN where ar and an are the tangential and normal acceleration components that are func- tions of the speed and curvature. Explain why an object with constant speed can still experience an acceleration. (c) Consider a trajectory r(t) = (t² – 1,t – t³).
