A jet pilot takes his aircraft in a vertical loop(adsbygoogle = window.adsbygoogle || []).push({});

(a) If the jet is moving at a speed of 1400 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.

I am having some trouble here. I converted the speed to be 389 m/s. I thought i would use the equation F=m(v^2/r) Then F would equal the normal force minus mg. But this does not seem to work out since we do not know the mass. I am a little confused. So any help would be great. Thanks
