A fighter pilot dives his plane toward the ground at 230 m/s. He pulls out of the dive on a vertical circle. What is the minimum radius of the circle, so that the normal force exerted on the pilot by his seat never exceeds three times his weight?
The greatest normal force on the pilot occurs at the lowest point on the circular path. At this point, the speed v = 230 m/sec is ...
The greatest normal force on the pilot is discovered.
