Week 2 problem 5 - problem 12.50

Hi, I'm Triet. I'm an undergrad at UC Irvine majoring in Aerospace Engineering. This is me suffering through the problems in MAE 80 - Dynamics to review for my Midterms/ Finals.

Disclaimer: No guarantee about the accuracy of the problem/ solution/ method. I may be wrong.

Problem: A 55-kg pilot flies a jet trainer in a half vertical loop of 1200-m radius so that the speed of the trainer decreases at a constant rate. Know that the plane has a speed of 550 km/h at point A (starting point of loop), and the pilot experiences weightlessness at point C ( i.e., the normal force from the seat bottom is zero). Determine (a) the deceleration of the plane, and (b) the force exerted on her by the seat of the trainer when the trainer is at point B (midway of the loop).
