the maximum normal force a pilot can withstand is about eight times his weight. What is the maximum radius of curvature that a jet planes pilot, pulling out of a vertical dive

Complete Question

the maximum force a pilot can stand is about seven times his weight. what is the minimum radius of curvature that a jet plane's pilot, pulling out of a vertical dive, can tolerate at a speed of 250m/s?

The value is    

Explanation:

From the question we are told that

 The  weight of the pilot is  

 The maximum force a pilot can withstand is  

 The speed is    

Generally the centripetal force acting on the pilot is equal to the net force acting on the pilot i.e

Here N  is the normal force acting on the pilot

Now

So

=>
