Q$4)$ Hockey player $\backslash ($ A $\backslash )$ passes the puck in the direction shown with a speed of $\backslash ($ v$\_\{$P$\}=8\backslash$mathrm$\{$~m$\}\backslash$cdot $\backslash$mathrm$\{$~s$\}^\{-1\}\backslash ).$ Her opponent, player $\backslash ($ B $\backslash ),$ moves in the direction shown to intercept the puck. There is no friction.

Draw a vector diagram to represent the relative and absolute velocity vectors of the puck and player B$.$

Calculate the absolute speed of player $\backslash ($ B$\backslash$left$($v$\_\{$B$\}\backslash$right$)\backslash )$ so that they intercept the puck.
