A jet pilot takes his aircraft in a vertical loop (a) If the jet is moving at a speed of 1200 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. m (b) Calculate also the 80 kg pilot's effective weight (the force with which the seat pushes up on him) at the bottom of the circle. N (c) Calculate the pilot's effective weight at the top of the circle. (Assume the same speed.)
