38. REASONINGThe normal force (magnitude FN) that the pilot’s seat exerts on him is part of the centripetal force that keeps him on the vertical circular path. However, there is another contribution to the centripetal force, as the drawing at the right shows. This additional contribution is the pilot’s weight (magnitude W). To obtain the ratio FN/W, we will apply Equation 5.3, which specifies the centripetal force as 2c/Fmvr=. SOLUTIONNoting that the direction upward (toward the center of the circular
