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
Part C
In terms of this model, what is her angular speed in the pike position?
