A diver dives from a high platform (Figure 11.102). When he leaves the platform, he tucks tightly and performs three complete revolutions in the air, then straightens out with his body fully extended before entering the water (Figure 11.103). He is in the air for a total time of 1.4 seconds. What is his angular speed ω just as he enters the water? Give a numerical answer. Be explicit about details of your model, and include (brief) explanations. You will need to estimate some quantities.
