Express your answer with the appropriate units.A diver leaves the platform with her body straight. Her body is in a relatively slow rotation, with an angular speed of 4.0 rad/s. She then tucks into a pike position, with her body essentially folded in half. We can use a simple model to understand what happens next. First, model her 50 kg,1.8 m body as uniform. Next, assume that when she goes into a pike position, shown in (Figure 1), she really does fold her body exactly in half. In terms of this model, what is her angular speed in the pike position? Express your answer in radians per second. In terms of this model, how many rotations does she complete in the 1.3 s that she holds the pike position? Express your answer as a number of rotations. Intial moment of intertia = 14 pike position inertia= 3.4
