An airline pilot climbs to a new flight level along the path shown. Knowing that the speed of the airplane decreases at a constant rate from 540 ft/s at point A to 480 ft/s at point C, determine the magnitude of the abrupt change in the force exerted on a 200-lb passenger as the airplane passes point B.
