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 varied. (Note: His apparent weight is equal to the magnitude of the force exerted by the seat on his body.)

A 70 kg stunt pilot begins pulling out of a dive into a vertical circle. If the plane’s speed at the lowest point of the circle is 80 m/s, what is the apparent weight of the pilot at the lowest point of the pullout? The pilot experiences a force of 5g from the centripetal acceleration at the bottom of the dive.
