End \( A \) of a rod \( A B \) is being pulled on the floor with a constant velocity \( \nu_{0} \) as shown. Taking the length of the rod as \( l \), at an instant when the rod makes an angle \( 37^{\circ} \) with the horizontal, calculate The velocity of the \( \mathrm{CM} \) of the rod
\( \mathrm{P} \)
W
(1) \( \frac{5}{7} v_{0} \) at \( \tan ^{-1} \frac{4}{3} \) below horizontal
(2) \( \frac{5}{7} v_{0} \) at \( \tan ^{-1} \frac{3}{4} \) below horizontal
(3) \( \frac{5}{6} v_{0} \) at \( \tan ^{-1} \frac{3}{4} \) below horizontal
(4) \( \frac{5}{6} v_{0} \) at \( \tan ^{-1} \frac{4}{3} \) below horizontal
