Problem $13\mathrm{.}160-$ Multiple package impacts

Packages in an automobile parts supply house are transported to the loading dock by pushing them along on a roller track with very little friction. At the instant shown, packages $B$ and $C$ are at rest, and package A has a velocity of $v_A=3\mathrm{.}500\frac{m}{s}.$ The coefficient of restitution between the packages is $0\mathrm{.}3.$

Problem $13\mathrm{.}160.$b $-$ Velocity after impact

Determine the velocity of A after it hits $B$ for the second time. $($Round the final answer to three decimal places.$)$

The velocity of A after it hits $B$ for the second time is
