A man having a weight of 180 lb crouches down on the end ofa diving board as shown. In this position, the radius ofgyration about his center of gravity is kG = 1.1 ft. Whileholding this position at θ = 0, he rotates about his toesat A until he loses contact with the board when θ= 90.
If he remains rigid, determine approximately how manyrevolutions he makes before striking the water after falling30 ft.
