An airplane flies in a loop (a circular path in a vertical plane) of radius 100 m . The pilot's head always points toward the center of the loop. The speed of the airplane is not constant; the airplane goes slowest at the top of the loop and fastest at the bottom.
a. What is the speed of the airplane at the top of the loop, where the pilot feels weightless?
b. What is the apparent weight of the pilot at the bottom of the loop, where the speed of the air-plane is 280 km/h? His true weight is 700 N.
