An object moving in an $xy$ horizontal plane has a velocity vec$(v),=(2$vec$(i)+2$hat$(j))\frac{m}{s}$ at a point in the whose position vector is vec$(\frac{?}{\text{b}\text{a}\text{r}}(r))=(10$hat$(i)+10$hat$(j))m$ relative to a stationary reference point on the plane. The object moves with constant acceleration for $10$ s and its velocity vector becomes $,q,=(22$hat$(i)+42$hat$(j))\frac{m}{s}$
