A jet pilot takes his aircraft in a vertical loop. As Part A shown in the figure(Figure 1). If the jet is moving at a speed of 1100 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 6.5 g's. Part B Calculate the 73 kg pilot's effective weight (the force with which the seat pushes up on him) at the bottom of the circle.
