A jet pilot takes his aircraft in a vertical loop.
(a) If the jet is moving at a speed of 1900 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 72 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.)
______N
