Q: An airline pilot climbs to a new flight level along the path shown. The motion of the airplane between A and B is defined by the relation s = 3t (180 - t), where s is the arc length in feet, t is the time in seconds, and t = 0 when the airplane is at point A. Determine the force exerted by his seat on a 165-lb passenger
(a) Just after the airplane passes point A,
