A 54 kg pilot flies a jet trainer in a half vertical loop of 1200 m radius so that the speed of the jet decreases at a constant rate. Knowing that the pilot's apparent weights at points A and C are NA = 1680 N and NC = 350N, respectively, determine the total force exerted on her by the seat of the jet trainer when the trainer is at point B.
