QUESTION:
(II) A diver (such as the one shown in Fig. 8–28) can reduce her moment of inertia by a factor of about 3.5 when changing from the straight 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?
ANSWER:Solution 54P
Step 1 of 3
The objective here is to determine the angular speed of the diver when she is in her straight position under the given conditions.
