I tried workin this problem out.. and it's not working!! --- An airplane is flying in a horizontal circle at a speed of 48.1 m/s. The 94.1 kg pilot does not want his radial acceleration to exceed 7:.39 g. The acceleration of gravity is 9.8 m/s^2 1) What is the minimum radius of the circular path? Answer in units of m. 7.39g (9.8m/s^2) = 72.422 m/s^2 do I need to square root 72.422?? 2) At this radius, what is the net centripetal force exerted on the pilot by the seat belts, the friction between him and the seat, and so forth? Answer in units of N. N = mg + m (V^2/m) is this the right formula?? what would m and v be??
