An airplane traveling at 480 km/h needs to
reverse its course. The pilot decides to accomplish this by banking the wings
at an angle of 38°. (a) Find the time needed to reverse course. (b) Describe any
additional force the passengers experience during the turn. [Hint: Assume an
aerodynamic “lift” force that acts perpendicularly to the flat wings; see Fig.
5 53.]
