DON'T SKIP ANY STEPS $14\mathrm{.}8$ Two identical cars A and $B$ are at rest on a loading dock with brakes released. Car $C,$ of a slightly different style but of the same weight, has been pushed by dockworkers and hits car $B$ with a velocity of $1\mathrm{.}5\frac{m}{s}.$ Knowing that the coefficient of restitution is $0\mathrm{.}8$ between $B$ and $C$ and $0\mathrm{.}5$ between A and $B,$ determine the velocity of each car after all collisions have taken place.
