The plot ofan airplane executes constant-speed loop-the-loop maneuver in vertical circle as in the figure below....
The pilot of an airplane executes a constant-speed loop-the-loop maneuver. His path is a vertical circle. The speed of the airplane is 250 mi/h, and the radius of the circle is 1350 ft. (a) What is the pilot's apparent weight at the lowest point if his true weight is 160 lb? (b) What is his apparent weight at the highest point? (c) What If? Describe how the pilot could experience weightlessness if both the radius and the speed can be...
The pilot of an airplane executes a constant-speed loop-the-loop maneuver. His path is a vertical circle. The speed of the airplane is 350 mi/h, and the radius of the circle is 1000 ft. (a) What is the pilot's apparent weight at the lowest point if his true weight is 160 lb? lb (b) What is his apparent weight at the highest point? lb (c) What If? Describe how the pilot could experience weightlessness if both the radius and the speed...
A jet pilot takes his aircraft in a vertical loop, as shown. If the jet is moving at a speed of 1140 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 7.0 g's? Calculate the 69-kg pilot's effective weight (the force with which the seat pushes up on him) at the bottom of the circle, and at the top of the circle...
