A jet pilot takes his aircraft in a vertical loop (Fig. 5-43).
(a) If the jet is moving at a speed of 1300km/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.
(b) Calculated the 78-kg pilot€™s effective weight (the force with which the seat pushes up on him) at the bottom of the circle, and
(c) At the top of the circle (assume the same speed).
