If the jet is moving at a speed of 1140 km/h at the lowest point of the loop, determine the minimum radius of the circle so that the centripetal acceleration at the lowest point does not exceed 6.0 g's.

The radius is  

Explanation:

From the question we are told that

   The speed is

   The centripetal acceleration is  

Generally the centripetal force acting on the jet is mathematically represented as  

Generally this centripetal force is equal to the net force acting which according to Newton's third law is mathematically  represented as

So

=>  

=>  

=>  

=>  

1/0.14nm = 10^10/1.4 a lot

attach the statements so i can answer : )
