A particle leaces the origin with an initial velocity $\overrightarrow{v}$ = ( 3.00 $\hat{i}$ ) m/s and a constant acceleration $\overrightarrow{a}$ = ( - 1.00$\hat{i}-0.500\hat{j}$ ) m/$s^2$ . When it reaches its maximum x coordinate , what are its velocity and position vector?

(i) Position vector U. -10$\hat{j}$

(ii) velocity vector V.4.5$\hat{i}-22.5\hat{j}$

W.4.5$\hat{i}-21.5\hat{j}$

X. -15$\hat{j}$
