A thin uniform rod is rotating at an angular velocity of `7.0 "rad"//s` about an axis that is perpendicular to the rod at its center. As the drawing indicates, the rod is hinged at two places, one-quarter of the length from each end. Without the aid of external torques, the rod suddenly assumes a u shape, with the arms of the u parallel to the rotation axis. What is the angular velocity of the rotating u?

A

`3.5 "rad"//s`

B

`7.0 "rad"//s`

C

`14 "rad"//s`

D

`1.8 "rad"//s`
