An airplane flies in a loop (a circular path in a vertical plane) of radius 150m . 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.
At the bottom of the loop, the speed of the airplane is 270km/h. What is the apparent weight of the pilot at this point? His true weight is 740N.
