${\to v}_{A B} = 5 \sqrt{5} \frac{m}{s} :angle is shown in figure$ $vec v_(AB)=5sqrt 5 m/s" :angle is shown in figure"$

Explanation:

$displacement of the objects : A B = \sqrt{2^{2} + 11^{2}}$ $"displacement of the objects : "AB=sqrt (2^2+11^2)$
$A B = \sqrt{4 + 121} = \sqrt{125} m$ $AB=sqrt (4+121)=sqrt 125 m$
${\to v}_{A B} = \frac{\sqrt{125}}{1}$ $vec v_(AB)=sqrt 125/1$
${\to v}_{A B} = 5 \sqrt{5} \frac{m}{s} :angle is shown in figure$ $vec v_(AB)=5sqrt 5 m/s" :angle is shown in figure"$
