1. The problem statement, all variables and given/known data A pilot of mass 50 kg comes out of a vertical dive in a circular arc such that her upward acceleration is 6g. (a) What is the magnitude of the force exerted by the airplane seat on the pilot at the bottom of the arc? (b) If the speed of the plane is 390 km/h, what is the radius of the circular arc? 2. Relevant equations Fc = (mv^2)/r (v^2/r)=a 3. The attempt at a solution (a) Fc = 50(6)(9.8) Fc = 2940 (b) 2940 = (50(360^2))/r r=2586.735 Apparently these answers are wrong and I have no idea why.
