$v = 3.28 \frac{m}{s}$ $v=3.28m/s$

$α = {113.96}^{o}$ $alpha=113.96 ^o$

Explanation:

$displacement of B from perspective of A :$ $" displacement of B from perspective of A :"$
$A B = \sqrt{9^{2} + 4^{2}}$ $AB=sqrt(9^2+4^2)$
$A B = \sqrt{81 + 16}$ $AB=sqrt(81+16)$
$A B = \sqrt{97}$ $AB=sqrt97$
$A B = 9.85 m$ $AB=9.85 " "m$

$v = \frac{A B}{t i m e}$ $v=(AB)/(time)$

$v = \frac{9.85}{3}$ $v=(9.85)/3$

$v = 3.28 \frac{m}{s}$ $v=3.28m/s$

$α = {113.96}^{o}$ $alpha=113.96 ^o$
