PLEASE SOLVE FOR BALL B BEING THE ONE WITH INITIAL VELOCITY INSTEAD OF BALL A$.$ Thank you

$14\mathrm{.}47$ Two small spheres A and $B,$ weighing $5lb$ and $2lb,$ respectivel$)$: are connected by a rigid rod of negligible weight. The two spleres are resting on a horizontal, frictionless surface when $A$ is suddenh: given the velocity $y_0=(10\mathrm{.}5\frac{f}{s})i.$ Determine $(a)$ the linear momentum of the system and its angular momenturn about its mass center $C,($b$)$ the velocities of A and $B$ after the rodAB lias rotated through $180.$

$14\mathrm{.}48$ Solve Prob. $14\mathrm{.}47,$ assuming that it is $B$ which is suddenly given the velocity $.$
