One of the limiting factors in high-performance aircraft is the number of g 's to which the pilot can be subjected without blacking out. The new F?22 Raptor fighter can achieve Mach 1.8 (1.8 times the speed of sound, which is about 340 m/s). Suppose a pilot dives in a circle and pulls up.

if the pilot cannot exceed 6.0g , or 6.0 times the normal acceleration of gravity, what is the tightest circle (smallest radius) in which the plane can turn?
