A pilot can withstand ten times the acceleration due to gravity, 10 g's, if he is wearing a special tight-fitting g-suit designed to keep the blood from rushing to his brain. (1 g = 9.80 m/s 2 ) An 85-kg pilot who is traveling east at 900. km/hr decides he want to go west. He makes a circle with 10 g's of acceleration.
a. What is the radius of the smallest circle in which the plane can turn around?
b. How much centripetal force acts on the pilot while he is in the turn?
