[填空题]
A diver (such as the one shown/ ixfkj8ix:f3c*j :57d eqnsk in Fig. 8–fqj5/hx s 0-dd29) can reduce her moment of inertia by a factor of about 3.5 when changing from the st qhx-df s0j5d/raight position to the tuck position. If she makes 2.0 rotations in 1.5 s when in the tuck position, what is her angular speed ($rev/s$) when in the straight position? $rev/s$
