Question: ( a ) _ ( B ) ( b ) A spin - stabilized spacecraft far from any other massive object initially rotates with vec

(a)
_(B)
(b)
A spin-stabilized spacecraft far from any other massive object initially rotates with vec(\omega )_(1)=-57kra(d)/(s) as it
translates along the z-axis. As shown in figure (a), the spacecraft consists of a rigid 212-kg cylinder-shaped
center module with (k_(G))_(z)=0.9m whose center of mass G lies along the z-axis and two 3.8-kg small weights
A and B that initially are fixed to the outer surface of the center module (r=1.99m). In order to reduce the
rotation rate, A and B are released on wires of negligible mass as shown in figure (b), where l=29m.
Find the magnitude of the spacecraft's resulting angular velocity, \omega _(2). Neglect the size of A and B.
CORRECT ANSWER: \omega 2=1.53984175715(rad)/(s).
