Physics
An airplane is flying in a horizontal circle at a speed of 104 m/s. the 85.0 kg pilot does not want the centripetal acceleration to exceed 6.35 times free-fall acceleration.
(a) find the minimum radius of the plane’s path.
(b) at this radius, what is the magnitude of the net force that maintains circular motion exerted on the pilot by the seat belts, the friction against the seat, and so forth?

Explanation:
Part A:
Airplane is moving in circular path so acceleration in circular path is given by:
Where:
V is the velocity of object in circular path
r is the radius of circular path
In order to find radius r. Above equation will become:
V=104 m/s
a_c=6.35*g=6.35*9.8=62.23 m/s^2
Part B:
Force on a object moving in a circular path is:
r=173.806 m
m=85 kg
V=104 m/s
