Problem $13\mathrm{.}167-$ The collision of two hockey pucks

Two identical hockey pucks are moving on a hockey rink at the same speed of $3\frac{m}{s}$ and in perpendicular directions when they strike each other as shown. Assuming a coefficient of restitution $e=0\mathrm{.}800,$ determine the magnitude and direction of the velocity of each puck after impact.

The velocity of puck A after impact, $v_A^{\text{'}}$ is

The direction of puck A after impact, $$

The velocity of puck $B$ after impact, $v_B^{\text{'}}$ is

The direction of puck $B$ after impact, $$

$\frac{m}{s}.($Round the final answer to three decimal places.$)$
