Problem (5) A 140 lb pilot of an airplane executes a vertical loop which in part follows the path of a "four-leaved rose" = (−400 cos 2thetatheta) ft, where thetatheta is measured in radians. If the pilot experiences weightlessness at point A while flying at a constant velocity, determine the speed of the airplane. Does your answer depend on the weight of the pilot?
