# Objects A and B are at the origin. If object A moves to (3 ,-4 ) and object B moves to (2 ,-6 ) over 4 s, what is the relative velocity of object B from the perspective of object A?

$\text{watch over the animation}$
${v}_{\text{AB"=sqrt5/4 " unit/s}}$

#### Explanation:

$\text{displacement for the object of A and B:}$
$\Delta s = \sqrt{{2}^{2} + {1}^{2}}$
$\Delta s = \sqrt{5}$
${v}_{\text{AB}} = \frac{\Delta s}{\Delta t}$
${v}_{\text{AB"=sqrt5/4 " unit/s}}$
The text passage contains a physics problem that involves calculating the relative velocity of two objects. The problem is presented as a question, and an answer is provided in the explanation section.
