An airplane is flying in a horizontal circle at a speed of 102 m/s. The 80.0 kg pilot does not want the centripetal acceleration to exceed 6.04...

The centripetal acceleration depends on the speed of the pilot and the radius of the path as



Since this acceleration cannot exceed 6.04 times free fall acceleration (acceleration due to gravity), the maximum value of the centripetal acceleration is


6.04* 9.81 = 59.25 m/s^2


Then, the minimal radius is determined by



The given speed of the pilot is 102 m/s, so

m.


The minimal radius of the plane's path is 175.6 meters.


The net force on the pilot, according to the second Newton's Law, equal mass times acceleration:


 , where m is the mass of the pilot. This net force creates the centripetal acceleration and thus maintains the circular motion.


 N.


The net force on the pilot equals 4,740 N.
